基于动目标模型,提出一种基于多脉冲积累的相参参数估计方法。
该方法通过对多脉冲信号进行快、慢时间匹配滤波处理,实现多脉冲相参积累;再利用互相关法进行相参参数估计。
仿真分析对比了不同脉冲个数和不同输入信噪比下的参数估计性能和相参性能,仿真结果表明,该方法具有可行性,且可以有效提高低信噪比情况下的参数估计性能和相参性能。

Accurate parameter estimation is the premise and core of good coherenceperformance. Based on the moving target model, a coherent parameter estimation method based onmulti-pulse accumulation is proposed. The method performs fast-time and slow-time match filtering formulti-pulse signals, and obtains the results of multi-pulse coherent accumulation. Then thecross-correlation method is utilized to estimate the coherent parameters. The performance of parameterestimation and correlation under different numbers of pulses and different input signal-to-noise ratios arecompared by simulation analysis. The simulation results show that the method is feasible and caneffectively improve the performance of parameter estimation and coherence in low signal-to-noise ratio.Keywords:distributed coherence;parameter estimation;moving target;multi-pulse accumulation分布式相参雷达(DCAR)因具有较好的探测性能、高角度分辨力、灵活性和机动性等一系列技术优势而成为目前国内外雷达领域研究热点[1-5]。

第27卷 第11期2007年11月 光 学 学 报AC TAO P TICA SIN ICAVol.27,No.11November ,2007文章编号:025322239(2007)112198027数字图像相关中基于位移场局部最小二乘拟合的全场应变测量3潘 兵 谢惠民(清华大学工程力学系,北京100084)摘要: 为了从含噪声的位移场中计算得到可靠的应变场,提出一种基于位移场局部最小二乘拟合的全场应变求解方法。
介绍了数字图像相关方法的原理,阐述了基于位移场局部最小二乘拟合的全场应变求解方法,并讨论了计算区域边界、孔洞及裂纹附近区域等情况下的应变计算。
对均匀变形和中心带圆孔的薄铝板拉伸实验的计算结果表明,该方法能有效地从原始位移场数据中提取全场应变信息。
在均匀变形情况下应选择大的应变计算窗口,计算结果更逼近真值;在非均匀变形情况下,如果位移场中包含较强的噪声,则应选择较大的应变计算窗口,而位移场精度很高时可选择更小的应变计算窗口。

a rX iv:c ond-ma t/974231v1[c ond-m at.str-el]28A pr1997First-principles calculations of the electronic structure and spectra of strongly correlated systems:dynamical mean-field theory V.I.Anisimov,A.I.Poteryaev,M.A.Korotin,A.O.Anokhin Institute of Metal Physics,Ekaterinburg,GSP-170,Russia G.Kotliar Serin Physics Laboratory,Rutgers University,Piscataway,New Jersey 08854,USA Abstract A recently developed dynamical mean-field theory in the iterated per-turbation theory approximation was used as a basis for construction of the ”first principles”calculation scheme for investigating electronic struc-ture of strongly correlated electron systems.This scheme is based on Local Density Approximation (LDA)in the framework of the Linearized Muffin-Tin-Orbitals (LMTO)method.The classical example of the doped Mott-insulator La 1−x Sr x TiO 3was studied by the new method and the results showed qualitative improvement in agreement with experimental photoemission spectra.1Introduction The accurate calculation of the electronic structure of materials starting from first principles is a challenging problem in condensed matter science since un-fortunately,except for small molecules,it is impossible to solve many-electron problem without severe approximations.For materials where the kinetic energy of the electrons is more important than the Coulomb interactions,the most successful first principles method is the Density Functional theory (DFT)within the Local (Spin-)Density Ap-proximation (L(S)DA)[1],where the many-body problem is mapped into a non-interacting system with a one-electron exchange-correlation potential approxi-mated by that of the homogeneous electron gas.It is by now,generally accepted that the spin density functional theory in the local approximation is a reliable starting point for first principle calculations1of material properties of weakly correlated solids(For a review see[2]).The situation is very different when we consider more strongly correlated materials, (systems containing f and d electrons).In a very simplified view LDA can be regarded as a Hartree-Fock approximation with orbital-independent(averaged) one-electron potential.This approximation is very crude for strongly correlated systems,where the on-cite Coulomb interaction between d-(or f-)electrons of transition metal(or rare-earth metal)ions(Coulomb parameter U)is strong enough to overcome kinetic energy which is of the order of band width W.In the result LDA gives qualitatively wrong answer even for such simple systems as Mott insulators with integer number of electrons per cite(so-called”undoped Mott insulators”).For example insulators CoO and La2CuO4are predicted to be metallic by LDA.The search for a”first principle”computational scheme of physical proper-ties of strongly correlated electron systems which is as successful as the LDA in weakly correlated systems,is highly desirable given the considerable impor-tance of this class of materials and is a subject of intensive current research. Notable examples offirst principle schemes that have been applied to srongly correlated electron systems are the LDA+U method[3]which is akin to orbital-spin-unrestricted Hartree-Fock method using a basis of LDA wave functions,ab initio unrestricted Hartree Fock calculations[4]and the use of constrained LDA to derive model parameters of model hamiltonians which are then treated by exact diagonalization of small clusters or other approximations[5].Many interesting effects,such as orbital and charge ordering in transition metal compounds were successfully described by LDA+U method[6].However for strongly correlated metals Hartree-Fock approximation is too crude and more sophisticated approaches are needed.Recently the dynamical mean-field theory was developed[7]which is based on the mapping of lattice models onto quantum impurity models subject to a self-consistency condition.The resulting impurity model can be solved by var-ious approaches(Quantum Monte Carlo,exact diagonalization)but the most promising for the possible use in”realistic”calculation scheme is Iterated Per-turbation Theory(IPT)approximation,which was proved to give results in a good agreement with more rigorous methods.This paper is thefirst in a series where we plan to integrate recent devel-ompements of the dynamical meanfield approach with state of the art band structure calculation techniques to generate an”ab initio”scheme for the cal-culation of the electronic structure of correlated solids.For a review of the historical development of the dynamical meanfield approach in its various im-plementations see ref[7].In this paper we implement the dynamical mean-field theory in the iterated perturbation theory approximation,and carry out the band structure calculations using a LMTO basis.The calculational scheme is described in section2.We present results obtained applying this method to La1−x Sr x TiO3which is a classical example of strongly correlated metal.22The calculation schemeIn order to be able to implement the achievements of Hubbard model theory to LDA one needs the method which could be mapped on tight-binding model.The Linearized Muffin-Tin Orbitals(LMTO)method in orthogonal approximation[8]can be naturally presented as tight-binding calculation scheme (in real space representation):H LMT O= ilm,jl′m′,σ(δilm,jl′m′ǫil n ilmσ+t ilm,jl′m′ c†ilmσ c jl′m′σ)(1)(i-site index,lm-orbital indexes).As we have mentioned above,LDA one-electron potential is orbital-inde-pendent and Coulomb interaction between d-electrons is taken into account in this potential in an averaged way.In order to generalize this Hamiltonian by including Coulomb correlations,one must add interaction term:1H int=Un d(n d−1)(3)2(n d= mσn mσtotal number of d-electrons).3In LDA-Hamiltonianǫd has a meaning of the LDA-one-electron eigenvalue for d-orbitals.It is known that in LDA eigenvalue is the derivative of the total energy over the occupancy of the orbital:ǫd=ddn d (E LDA−E Coul)=ǫd−U(n d−12)(7)(q is an index of the atom in the elementary unit cell).In the dynamical mean-field theory the effect of Coulomb correlation is de-scribed by self-energy operator in local approximation.The Green function is:G qlm,q′l′m′(iω)=1The chemical potential of the effective medium µis varied to satisfy Luttinger theorem condition:1d(iωn)Σ(iωn)=0(11)In iterated perturbation theory approximation the anzatz for the self-energy is based on the second order perturbation theory term calculated with”bath”Green function G0:Σ0(iωs)=−(N−1)U21kT,Matsubara frequenciesωs=(2s+1)πβ;s,n integer numbers.The termΣ0is renormalized to insure correct atomic limit:Σ(iω)=Un(N−1)+AΣ0(iω)β iωn e iωn0+G(iωn)),B=U[1−(N−1)n]−µ+ µn0(1−n0)(15)n0=1iω+µ−∆(iω)+δµ+n(N−1)β iωn e iωn0+G CP A(iωn)(18) D[n]=n iωn e iωn0+1energy to time variables and back:G0(τ)=1V Bd k[z−H(k,z)]−1(24)After diagonalization,H(k,z)matrix can be expressed through diagonal matrix of its eigenvalues D(k,z)and eigenvectors matrix U(k,z):H(k,z)=U(k,z)D(k,z)U−1(k,z)(25) and Green function:G(z)=1V Bd k U in(k,z)U−1nj(k,z)V Bvd kU in(k,z)U−1nj(k,z)V B(28)6v is tetrahedron volumer n i=(z−D n(k i,z))2k(=j)(D n(k k,z)−D n(k j,z))ln[(z−D n(k j,z))/(z−D n(k i,z)]1+a2(z−z2)1(30)where the coefficients a i are to be determined so that:C M(z i)=u i,i=1,...,M(31) The coefficients a i are then given by the recursion:a i=g i(z i),g1(z i)=u i,i=1,...,M(32)g p(z)=g p−1(z p−1)−g p−1(z)3ResultsWe have applied the above described calculation scheme to the doped Mott insulator La1−x Sr x TiO3is a Pauli-paramagnetic metal at room tem-perature and below T N=125K antiferromagnetic insulator with a very small gap value(0.2eV).Doping by a very small value of Sr(few percent)leads to the transition to paramagnetic metal with a large effective mass.As photoemission spectra of this system also show strong deviation from the noninteracting elec-trons picture,La1−x Sr x TiO3is regarded as an example of strongly correlated metal.The crystal structure of LaTiO3is slightly distorted cubic perovskite.The Ti ions have octahedral coordination of oxygen ions and t2g-e g crystalfield splitting of d-shell is strong enough to survive in solid.On Fig.1the total and partial DOS of paramagnetic LaTiO3are presented as obtained in LDA calculations (LMTO method).On3eV above O2p-band there is Ti-3d-band splitted on t2g and e g subbands which are well separated from each other.Ti4+-ions have d1 configuration and t2g band is1/6filled.As only t2g band is partiallyfilled and e g band is completely empty,it is reasonable to consider Coulomb correlations between t2g−electrons only and degeneracy factor N in Eq.(12)is equal6.The value of Coulomb parameter U was calculated by the supercell procedure[9]regarding only t2g−electrons as localized ones and allowing e g−electrons participate in the screening.This cal-culation resulted in a value3eV.As the localization must lead to the energy gap between electrons with the same spin,the effective Coulomb interaction will be reduced by the value of exchange parameter J=1eV.So we have used effective Coulomb parameter U eff=2eV.The results of the calculation for x=0.06(dop-ing by Sr was immitated by the decreasing on x the total number of electrons) are presented in the form of the t2g-DOS on Fig.2.Its general form is the same as for model calculations:strong quasiparticle peak on the Fermi energy and incoherent subbands below and above it corresponding to the lower and upper Hubbard bands.The appearance of the incoherent lower Hubbard band in our DOS leads to qualitatively better agreement with photoemission spectra.On Fig.3the exper-imental XPS for La1−x Sr x TiO3(x=0.06)[12]is presented with non-interacting (LDA)and interacting(IPT)occupied DOS broadened to imitate experimental resolution.The main correlation effect:simultaneous presence of coherent and incoherent band in XPS is successfully reproduced in IPT calculation.However, as one can see,IPT overestimates the strength of the coherent subband.4ConclusionsIn this publication we described how one can interface methods for realistic band structure calculations with the recently developed dynamical meanfield8technique to obtain a fully”ab initio”method for calculating the electronic spectra of solids.With respect to earlier calculations,this work introduces several method-ological advances:the dynamical meanfield equations are incorporated into a realistic electronic structure calculation scheme,with parameters obtained from afirst principle calculation and with the realistic orbital degeneracy of the compound.To check our method we applied to doped titanates for which a large body of model calculation studies using dynamical meanfield theory exists.There results are very encouraging considering the experimental uncertainties of the analysis of the photoemission spectra of these compounds.We have used two relative accurate(but still approximate)methods for the solution of the band structure aspect and the correlation aspects of this problem:the LMTO in the ASA approximation and the IPT approximation. In principle,one can use other techniques for handling these two aspects of the problem and further application to more complicated materials are necessary to determine the degree of quantitative accuracy of the method.9References[1]Hohenberg P.and Kohn W.,Phys.Rev.B136,864(1964);Kohn W.andSham L.J.,ibid.140,A1133(1965)[2]R.O.Jones,O.Gunnarsson,Reviews of Modern Physics,v61,689(1989)[3]Anisimov V.I.,Zaanen J.and Andersen O.K.,Phys.Rev.B44,943(1991)[4]S.Massida,M.Posternak, A.Baldareschi,Phys.Rev.B46,11705(1992);M.D.Towler,N.L.Allan,N.M.Harrison,V.R.Sunders,W.C.Mackrodt,E.Apra,Phys.Rev.B50,5041(1994);[5]M.S.Hybertsen,M.Schlueter,N.Christensen,Phys.Rev.B39,9028(1989);[6]Anisimov V.I.,Aryasetiawan F.and Lichtenstein A.I.,J.Phys.:Condens.Matter9,767(1997)[7]Georges A.,Kotliar G.,Krauth W.and Rozenberg M.J.,Reviews of ModernPhysics,v68,n.1,13(1996)[8]O.K.Andersen,Phys.Rev.B12,3060(1975);Gunnarsson O.,Jepsen O.andAndersen O.K.,Phys.Rev.B27,7144(1983)[9]Anisimov V.I.and Gunnarsson O.,Phys.Rev.B43,7570(1991)[10]Lambin Ph.and Vigneron J.P.,Phys.Rev.B29,3430(1984)[11]Vidberg H.J.and Serene J.W.,Journal of Low Temperature Physics,v29,179(1977)[12]A.Fujimori,I.Hase,H.Namatame,Y.Fujishima,Y.Tokura,H.Eisaki,S.Uchida,K.Takegahara,F.M.F de Groot,Phys.Rev.Lett.69,1796(1992).(Actually in this article the chemical formula of the sample was LaTiO3.03, but the excess of oxygen produce6%holes which is equivalent to doping of 6%Sr).105Figure captionsFig.1.Noninteracting(U=0)total and partial density of states(DOS)for LaTiO3.Fig.2.Partial(t2g)DOS obtained in IPT calculations in comparison with noninteracting DOS.Fig.3.Experimental and theoretical photoemission spectra of La1−x Sr x TiO3 (x=0.06).11)LJ 7L G H J '26 V W D W H H 9 D W R P (QHUJ\ H97L G W J7RWDO /D7L2 '26 V W D W H H 9 F H O O3HUWXUEDWHG)LJ'26 V W D W H V H 9 (QHUJ\ H98QSHUWXUEDWHG,Q W H Q V L W \ H 9(QHUJ\ H9。

P.O.Box 2008Oak Ridge,TN 37831-6173,USA3Theoretical Physics III,Center for Electronic Correlations and Magnetism,Institute of Physics,University of Augsburg,Augsburg 86135,GermanyFirst principles constrained density functional theory scheme in Wannier functions formalism has been used to calculate Coulomb repulsion U and Hund’s exchange J parameters for iron 3d electrons in LaFeAsO.Results strongly depend on the basis set used in calculations:when O-2p ,As-4p ,and Fe-3d orbitals and corresponding bands are included,computation results in U =3÷4eV,however,with the basis set restricted to Fe-3d orbitals and bands only,computation gives parameters corre-sponding to F 0=0.8eV,J =0.5eV.LDA+DMFT (the Local Density Approximation combined with the Dynamical Mean-Field Theory)calculation with this parameters results in weakly correlated electronic structure that is in agreement with X-ray experimental spectra.PACS numbers:74.25.Jb,71.45.GmFollowing the discovery of high-T c superconductivity in iron oxypnictide LaO 1−x F x FeAs [1],a question of the in-fluence of electronic correlation effects on the normal and superconducting properties of LaFeAsO has arisen.In striking similarity with high-T c cuprates,undoped mate-rial LaFeAsO is not superconducting with antiferromag-netic commensurate spin density wave developing below 150K [2].Only when electrons (or holes)are added to the system via doping,antiferromagnetism is suppressed and superconductivity appears.As it is generally accepted that Coulomb correlations between copper 3d electrons are responsible for cuprates anomalous properties,it is tempting to suggest that the same is true for iron 3d electrons in LaFeAsO.Correlation strength in a system is determined by ra-tio of Coulomb interaction parameter U and band width W .If U/W is significantly less than 1then the system is weakly correlated and results of the Density Functional Theory (DFT)calculations are reliable enough to explain its electronic and magnetic properties.However,if U value is comparable with W or even larger then the sys-tem is in intermediate or strongly correlated regime and Coulomb interactions must be explicitly treated in elec-tronic structure calculations.For LaFeAsO the bands formed by Fe-3d states have width ≈4eV (see shaded area in the lower panel of Fig.1),so an estimation for Coulomb interaction parameter U should be compared with this value.In practical calculations,U is often considered as a free parameter to achieve the best agreement of calcu-lated and measured properties of investigated system.Sometimes U value could be estimated from the experi-mental spectra.The first principles justified methods to determine Coulomb interaction parameter U value are constrained DFT scheme [3],where in DFT calculations the d -orbital occupancies are fixed to the certain values and U is numerically determined as a derivative of d -orbital energy over its occupancy and Random Phase Approximation (RPA)method,where screened Coulomb interaction between d -electrons is calculated via pertur-bation theory [4].In Ref.5it was proposed to use in LaFeAsO U =4eV obtained in RPA calculations for metallic iron [6].This value for Coulomb parameter (with Hund’s ex-change parameter J =0.7eV)was used in Dynami-cal Mean-Field Theory (DMFT)[7]calculations for LaFeAsO [5,8,9].Results of these works show iron 3d electrons being in intermediate or strongly correlated regime,as it is natural to be expected for Coulomb pa-rameter value U =4eV and Fe-3d band width ≈4eV.The most direct way to estimate correlation effects strength in a system under consideration is to compare the experimental spectra with densities of states (DOS)obtained in DFT calculations.For strongly correlated materials additional features in the experimental pho-toemission and absorption spectra appear that are inter-preted as lower and upper Hubbard bands absent in the DFT DOS.If no such additional features are observed and DOS obtained in DFT calculations satisfactorily de-scribe the experimental spectra then the material is in weakly correlated regime.LaFeAsO was studied by soft X-ray absorption and emission spectroscopy [10],X-ray absorption spec-troscopy (O K -edge)[11]and photoemission spec-troscopy [12].In all these works the conclusion was that DOS obtained in DFT calculations gave good agreement with the experimental spectra and the estimations for Coulomb parameter value are U <1eV [11].That con-tradiction with results of the DMFT calculations [5,8,9]shows that first principles calculation of Coulomb inter-action parameter U value for LaFeAsO is needed to de-termine the correlation effects strength in this material.Results of such calculations by constrained DFT calcula-tions are reported in the present work.We have obtained2the value U<1eV for Fe-3d band that agrees with the estimates from spectroscopy.Recently the RPA calcula-tions for Coulomb interaction parameter U in LaFeAsO were reported,where U was estimated as1.8÷2.7eV[13]. It is important to notethat Coulomb interaction pa-rameter U value depends on the model where it will be used and,more precisely,on the choice of the orbital set that is taken explicitly into account in the model. For example,in constrained DFT calculations for high-T c cuprates the resulting U value for Cu d-shell was found between8and10eV[14].The U value in this range was used in cluster calculations where all Cu d-orbitals and p-orbitals of neighboring oxygens were taken into ac-count and calculated spectra agree well with experimen-tal data[15].However,in one band model,where only x2−y2orbital per cooper atom is explicitly included in the calculations,the U value giving good agreement with experimental data falls down to2.5÷3.6eV[16],that is 3-4times smaller than constrained DFT value.The same situation occurs for titanium and vanadium oxides:the U value from constrained DFT calculations is≈6eV and cluster calculations where all d-orbitals and p-orbitals of neighboring oxygens were taken into account with U close to this value gave good agreement between calculated and experimental spectra[17].However,in the model where only partiallyfilled t2g orbitals are in-cluded,much smaller U value(corresponding to Slater integral F0=3.5eV)gives the results in agreement withexperimental data[18].It is interesting that such a small U value can be ob-tained in constrained DFT calculations for titanates and vanadates where only t2g-orbital occupancies arefixed while all the other states(e g-orbitals of vanadium and p-orbitals of oxygens)allowed to relax in self-consistent iterations[18,19].So the calculation scheme used in constrained DFT(the set of the orbitals withfixed occu-pancies)should be consistent with basis set of the model where the calculated U value will be used.Another source of uncertainty in constrained DFT calculation scheme is a definition of atomic orbitals whose occupancies arefixed and energy calculated.In some DFT methods,like Linearized Muffin-Tin Orbitals (LMTO)[20],these orbitals could be identified with LMTO.However,in other DFT calculation schemes, where plane waves are used as a basis,like in pseudopo-tential method[21]one should use more general definition for localized atomic like orbitals such as Wannier func-tions(WFs)[22].The practical way to calculate WFs for specific materials using projection of atomic orbitals on Bloch functions was developed in[23].In Fig.1the total and partial DOS for LaFeAsO ob-tained in LMTO calculations are shown.Crystalfield splitting for Fe-3d orbitals in this material is rather weak (∆cf=0.25eV)and allfive d orbitals of iron form com-mon band in the energy region(−2,+2)eV relative to the Fermi level(see grey region on the bottom panel in byforpredominantly formed by Fe-3d orbitals in the energy window(−2,+2)eV and equal number of Fe-3d orbitals to be projected on the Bloch functions for these bands. That choice corresponds to the model where onlyfive d-orbital per Fe site are included but all arsenic and oxygen3FIG.2:(Color online)Module square of d x2−y2-like Wannier function computed for Fe-3d bands only(left panel)and for full set of O-2p,As-4p and Fe-3d bands(right panel).Big sphere in the center marks Fe ion position and four small spheres around it correspond to As neighbors.p-orbitals are omitted.Second choice includes all bands in energy window(−5.5,+2)eV that are formed by O-2p,As-4p and Fe-3d states and correspondingly full set of O-2p,As-4p and Fe-3d atomic orbitals to be projected on Bloch functions for these bands.That would correspond to the extended model where in addition to d-orbitals all p-orbitals are included too.In both cases we obtained Hamiltonian in WF basis that reproduces exactly bands predominantly formed by Fe-3d states in the energy window(−2,+2)eV(Fig.1), but in the second case in addition to that bands formed by p-orbitals in the energy window(−5.5,−2)eV will be reproduced too.However,WFs with d-orbital symmetry computed in those two cases have very different spatial distribution.In Fig.2the module square of d x2−y2-like WF is plotted.While for the case when full set of bands and atomic orbitals was used(right panel)WF is nearly pure atomic d-orbital(iron states contribute99%),WF computed using Fe-3d bands only is much more extended in space(left panel).It has significant weight on neigh-boring As ions with only67%contribution from central iron atom.The physical reason for such effect is p−d hybridiza-tion that is treated explicitly in the case where both p-and d-orbitals are included.In the case where only Fe-3d bands are included in calculation p−d hybridization re-veals itself in the shape of WF.Fe-3d bands in the energy window(−2,+2)eV correspond to antibonding combi-nation of Fe-3d and As-4p states and that is clearly seen on the left panel of Fig.2.The different spatial distribution for two WFs calcu-lated with full and restricted orbital bases can be ex-pected to lead to different effective Coulomb interaction for electrons occupying these states.The results of con-strained DFT calculations of the average Coulomb inter-action¯U and Hund’s exchange J parameters for electrons on WFs computed with two different set of bands and orbitals(and using two different DFT methods:LMTO and pseudopotential)are presented in Tab.I.TABLE I:The constrained DFT calculated values of average Coulomb interaction¯U and Hund’s exchange J(eV)param-eters for d-symmetry Wannier functions computed with two different sets of bands and orbitals.separate Fe-3d bandTB-LMTO-ASA¯U=3.10,J=0.81 PWSCF¯U=4.00,J=1.024Usoftand emission spectroscopy study[10].It was concluded there that LaFeAsO does not represent strongly corre-lated system since Fe L3X-ray emission spectra do not show any features that would indicate the presence of the low Hubbard band or the quasiparticle peak that were predicted by the LDA+DMFT analysis[5,8,9]with the large U=4eV.A comparison of the X-ray absorption spectra(O K-edge)with the LDA calculations gave an upper limit of the on-site Hubbard U≈1eV[11].Pho-toemission spectroscopy study of LaFeAsO suggests[12] that the line shapes of Fe2p core-level spectra corre-spond to an itinerant character of Fe3d electrons.It was demonstrated there that the valence-band spectra are generally consistent with band-structure calculations except for the shifts of Fe3d-derived peaks toward the Fermi level.In conclusion,we have calculated the values of U and J via constrained DFT procedure in the basis of WFs.For minimal model including only Fe-3d orbitals we have ob-tained Coulomb parameters F0=0.8eV,J=0.5eV.Thecalculation with these parameters results weakly correlated nature of iron d bands in this com-This conclusion is supported by several X-ray investigations of this material.Support by the Russian Foundation for Basic Research Grant No.RFFI-07-02-00041,Civil Research andFoundation together with Russian Min-of science and education through program Y4-P-Russian president grant for young scientists MK-and Dynasty Foundation is gratefully ac-J.K.acknowledges the support of SFB484 the Deutsche Forschungsgemeinschaft.Y.Kamihara et al.,J.Am.Chem.Soc.130,3296(2008).M.A.McGuire et al.,arXiv:0804.0796;C.de la Cruz et al.,Nature453,899(2008).P.H.Dederichs et al.,Phys.Rev.Lett.53,2512(1984);O.Gunnarsson et al.,Phys.Rev.B39,1708(1989);V.I.Anisimov et al.,ibid.43,7570(1991).I.V.Solovyev et al.,Phys.Rev.B71,045103(2005);F.Aryasetiawan et al.,ibid.74,125106(2006).K.Haule et al.,Phys.Rev.Lett.100,226402(2008).T.Miyake et al.,Phys.Rev.B77,085122(2008).A.Georges et al.,Rev.Mod.Phys.68,13(1996).L.Craco et al.,arXiv:0805.3636.A.O.Shorikov et al.,arXiv:0804.3283.E.Z.Kurmaev et al.,arXiv:0805.0668.T.Kroll et al.,arXiv:0806.2625.W.Malaeb et al.,arXiv:0806.3860.K.Nakamura et al.,arXiv:0806.4750.[14]M.S.Hybertsen et al.,Phys.Rev.B39,9028(1989);M.S.Hybertsen et al.,ibid.41,11068(1990);
