a rXiv:074.1898v1[he p-th]15A pr27Electromagnetic Casimir densities for a wedge with a coaxial cylindrical shell A.A.Saharian ∗Department of Physics,Yerevan State University,1Alex Manoogian Street,375025Yerevan,Armenia February 1,2008Abstract Vacuum expectation values of the field square and the energy-momentum tensor for the electromagnetic field are investigated for the geometry of a wedge with a coaxal cylindrical boundary.All boundaries are assumed to be perfectly conducting and both regions inside and outside the shell are considered.By using the generalized Abel-Plana formula,the vacuum expectation values are presented in the form of the sum of two terms.The first one corresponds to the geometry of the wedge without the cylindrical shell and the second term is induced by the presence of the shell.The vacuum energy density induced by the shell is negative for the interior region and is positive for the exterior region.The asymptotic behavior of the vacuum expectation values are investigated in various limiting cases.It is shown that the vacuum forces acting on the wedge sides due to the presence of the cylindrical boundary are always attractive.PACS numbers:03.70.+k 1Introduction The Casimir effect is among the most interesting macroscopic manifestations of vacuum fluctu-ations.It have important implications on all scales,from cosmological to subnuclear,and has become in recent decades an increasingly popular topic in quantum field theory.In addition to its fundamental interest the Casimir effect also plays an important role in the fabrication and operation of nano-and micro-scale mechanical systems.The imposition of boundary conditions on a quantum field leads to the modification of the spectrum for the zero-point fluctuations and results in the shift in the vacuum expectation values for physical quantities such as the energy density and stresses.In particular,the confinement of quantum fluctuations causes forces that act on constraining boundaries.The particular features of the resulting vacuum forces depend on the nature of the quantum field,the type of spacetime manifold,the boundary geometries and the specific boundary conditions imposed on the field.Since the original work by Casimir [1]many theoretical and experimental works have been done on this problem (see,e.g.,[2,3,4,5]and references therein).Many different approaches have been used:mode summation methodwith combination of the zeta function regularization technique,Green function formalism,mul-tiple scattering expansions,heat-kernel series,etc.Advancedfield-theoretical methods have been developed for Casimir calculations during the past years[6,7,8].However,there are still difficulties in both interpretation and renormalization of the Casimir effect.Straightforward computations of geometry dependencies are conceptually complicated,since relevant informa-tion is subtly encoded in thefluctuations spectrum[8].Analytic solutions can usually be found only for highly symmetric geometries including planar,spherically and cylindrically symmetric boundaries.Recently the Casimir energy has been evaluated exactly for several less symmetric configurations of experimental interest.These include a sphere in front of a plane and a cylinder in front of a plane[9].A great deal of attention received the investigations of quantum effects for cylindrical bound-aries.In addition to traditional problems of quantum electrodynamics under the presence of material boundaries,the Casimir effect for cylindrical geometries can also be important to the flux tube models of confinement[10,11]and for determining the structure of the vacuum state in interactingfield theories[12].The calculation of the vacuum energy of electromagneticfield with boundary conditions defined on a cylinder turned out to be technically a more involved problem than the analogous one for a sphere.First the Casimir energy of an infinite perfectly conducting cylindrical shell has been calculated in Ref.[13]by introducing ultraviolet cutoffand later the corresponding result was derived by zeta function technique[14,15,16].The local characteristics of the corresponding electromagnetic vacuum such as energy density and vacuum stresses are considered in[17]for the interior and exterior regions of a conducting cylindrical shell,and in[18]for the region between two coaxial shells(see also[19]).The vacuum forces acting on the boundaries in the geometry of two cylinders are also considered in Refs.[20]. The scalar Casimir densities for a single and two coaxial cylindrical shells with Robin boundary conditions are investigated in Refs.[21,22].Less symmetric configuration of two eccentric per-fectly conducting cylinders is considered in Ref.[23].Vacuum energy for a perfectly conducting cylinder of elliptical section is evaluated in Ref.[24]by the mode summation method,using the ellipticity as a perturbation parameter.The Casimir forces acting on two parallel plates inside a conducting cylindrical shell are investigated in Ref.[25].Aside from their own theoretical and experimental interest,the exactly solvable problems with this type of boundaries are useful for testing the validity of various approximations used to deal with more complicated geometries.From this point of view the wedge with a coaxial cylindrical boundary is an interesting system,since the geometry is nontrivial and it includes two dynamical parameters,radius of the cylindrical shell and opening angle of the wedge.This geometry is also interesting from the point of view of general analysis for surface divergences in the expectation values of local physical observables for boundaries with discontinuities.The nonsmoothness of the boundary generates additional contributions to the heat kernel coefficients (see,for instance,the discussion in[26,27,28]and references therein).The present paper is concerned with local analysis of the vacuum of the electromagneticfield constrained to satisfy perfectly conducting boundary conditions on boundary surfaces of a wedge with a coaxial cylin-drical ly,we will study the vacuum expectation values of thefield squares and the energy-momentum tensor for the electromagneticfield for both regions inside and outside the cylindrical shell.In addition to describing the physical structure of the quantumfield at a given point,the energy-momentum tensor acts as the source of gravity in the Einstein equa-tions.It therefore plays an important role in modelling a self-consistent dynamics involving the gravitationalfield.The vacuum expectation value of the square of the electricfield determines the electromagnetic force on a neutral polarizable particle.Some most relevant investigations to the present paper are contained in Refs.[2,29,30,31,32,33],where the geometry of a wedge without a cylindrical boundary is considered for a conformally coupled scalar and electromag-neticfields in a four dimensional spacetime.The total Casimir energy of a semi-circular infinite cylindrical shell with perfectly conducting walls is considered in[34]by using the zeta function technique.For a scalarfield with an arbitrary curvature coupling parameter the Wightman function,the vacuum expectation values of thefield square and the energy-momentum tensor in the geometry of a wedge with an arbitrary opening angle and with a cylindrical boundary are evaluated in[35,36].Note that,unlike the case of conformally coupledfields,for a general coupling the vacuum energy-momentum tensor is angle-dependent and diverges on the wedge sides.Our method here employs the mode summation and is based on a variant of the gen-eralized Abel-Plana formula[37](see also Refs.[19,38]).This enables us to extract from the vacuum expectation values the parts due to a wedge without the cylindrical shell and to present the parts induced by the shell in terms of strongly convergent integrals.Note that the closely related problem of the vacuum densities induced by a cylindrical boundary in the geometry of a cosmic string is investigated in Refs.[39,40]for both scalar and electromagneticfields.We have organized the paper as follows.In the next section we describe the structure of the modes for a wedge with a cylindrical shell in the region inside the shell.By applying to the corresponding mode sums the generalized Abel-Plana formula,we evaluate the vacuum expectation values of the electric and magneticfield square.Various limiting cases of the general formulae are discussed.Section3is devoted to the investigation of the vacuum expectation values for the energy-momentum tensor of the electromagneticfield in the region inside the shell.The additional vacuum forces acting on the wedge sides due to the presence of the cylindrical boundary are evaluated.In section4we consider the vacuum densities for a wedge with the cylindrical shell in the exterior region with respect to the shell.Formulae for the shell contributions are derived and the corresponding surface divergences are investigated.The vacuum forces acting on the wedge sides are discussed.The main results are summarized and discussed in section5.2Vacuum expectation values of thefield square inside a cylin-drical shellConsider a wedge with the opening angleφ0and with a coaxial cylindrical boundary of radius a(seefigure1)assuming that all boundaries are perfectly conducting.In accordance with the problem symmetry,in the discussion below the cylindrical coordinates(r,φ,z)will be used.We are interested in the vacuum expectation values(VEVs)of thefield square and the energy-momentum tensor for the electromagneticfield.Expanding thefield operator in terms of the creation and annihilation operators and using the commutation relations,the VEV for a quantity F{A i,A k}bilinear in thefield can be presented in the form of the mode-sum0|F{A i,A k}|0 = αF{Aαi,A∗αk},(1)where{Aαi,A∗αk}is a complete set of solutions of the classicalfield equations satisfying the boundary conditions on the bounding surfaces and specified by a set of quantum numbersα.In accordance with formula(1),for the evaluation of the VEVs for the square of the electric and magneticfields and the energy-momentum tensor,the corresponding eigenfunctions are needed.In this section we consider the region inside the cylindrical shell(region I infigure 1).For the geometry under consideration there are two different types of the eigenfunctions corresponding to the transverse magnetic(TM)and transverse electric(TE)waves.In the discussion below we will specify these modes by the indexλ=0andλ=1for the TM and TE waves respectively.In the Coulomb gauge,the vector potentials for the TM and TE modes areδαα′,(4)ωwhere the integration goes over the region inside the shell.From this condition,by using the standard integral involving the square of the Bessel function,onefinds4qT qm(γa)β2α=ascending order.Consequently,the eigenfunctions are specified by the set of quantum numbers α=(k,m,λ,n ).First we consider the VEVs of the squares of the electric and magnetic fields inside the shell.Substituting the eigenfunctions(2)intothecorrespondingmode-sum formula,we find0|F 2|0 =4q2∞0dx f (x )+πJ (λ)qm (z )−1I (λ)qm (x ) e −qmπi f (e πi/2x )+e qmπi f (e −πi/2x ) ,(12)where Y ν(z )is the Neumann function and I ν(z ),K ν(z )are the modified Bessel functions.As it can be seen,for points away from the shell the contribution to the VEVs coming from the second integral term on the right-hand side of (12)is finite in the limit µ→0and,hence,the cutofffunction in this term can be safely removed.As a result the VEVs can be written in the form 0|F 2|0 = 0w |F 2|0w + F 2cyl ,(13)where0w |F 2|0w =qγ2 J ′2qm (γr )+q 2m 2γ2r 2 J 2qm (γr ) ,(14)and F 2 cyl =8q I (λ)qm (xa )G (ηF λ)[k,Φ(λ)qm (φ),I qm (xr )]x 2−k 2.(15)In formula Eq.(15)we have introduced the notationsG (0)[k,Φ(φ),f (x )]=(k 2r 2/x 2) Φ2(φ)f ′2(x )+Φ′2(φ)f 2(x )/x 2 +Φ2(φ)f 2(x ),(16)G (1)[k,Φ(φ),f (x )]=(k 2r 2/x 2−1)Φ2(φ)f ′2(x )+Φ′2(φ)f 2(x )/x 2 .(17)The second term on the right-hand side of Eq.(13)vanishes in the limit a →∞and the first one does not depend on a .Thus,we can conclude that the term 0w|F 2|0w corresponds to the part in the VEVs when the cylindrical shell is absent with the corresponding vacuum state |0w .Hence,the application of the generalized Abel-Plana formula enables us to extract from the VEVs the parts induced by the cylindrical shell without specifying the cutofffunction.In addition,these parts are presented in terms of the exponentially convergent integrals.First,let us concentrate on the part corresponding to the wedge without a cylindrical shell.First of all we note that in Eq.(14)the part which does not depend on the angular coordinate φis the same as in the corresponding problem of the cosmic string geometry with the angle deficit 2π−φ0(see Ref.[40]),which we will denote by 0s |F 2|0s .For this part we have0s |F 2|0s =qγ2 J ′2qm (γr )+q 2m2180πr 4,(18)where 0M|F 2|0Mis the part corresponding to the Minkowskian spacetime without boundaries and in the last expression we have removed the cutoff.To evaluate the part in (14)whichdepends on φ,we firstly consider the case when the parameter q is an integer.In this case the summation over m can be done by using the formula [41,42]∞ ′m =0cos(2qmφ)J 2qm (y )=1y 2 J 2qm (y ) =−1Substituting this in formula(14),the integrals remained are evaluated by introducing polar coordinates in the(k,γ)-plane.In this way onefinds0w|F2|0w = 0s|F2|0s −3(−1)ηF1180πr4−(−1)ηF1q22sin2(qφ)+1−q2 ,(23)withηE1=1andηB1=0.Though we have derived this formula for integer values of theparameter q,by the analytic continuation it is valid for non-integer values of this parameter aswell.The expression on the right of formula(23)is invariant under the replacementφ→φ0−φand,as we could expect,the VEVs are symmetric with respect to the half-planeφ=φ0/2.Formula(23)for F=E was derived in Ref.[32]within the framework of Schwinger’s sourcetheory.For q=1from formula(23)as a special case we obtain the renormalized VEVs of thefield square for a conducting plate.In this case x=r sinφis the distance from the plate andone hasF2 pl,ren=−3(−1)ηF1180x40−(−1)ηF1π32sin2(πx/x0)−1.(25)Now,we turn to the investigation of the parts in the VEVs of thefield square induced by the cylindrical boundary and given by formula(15).By using the formula∞dk k m ∞k dx xf(x)x2−k2=√2 2+1 ∞0dx x m+1f(x),(26) these parts are presented in the formF2 cyl=2qI(λ)qm(xa)G(ηFλ)[Φ(λ)qm(φ),I qm(xr)].(27) Here,for given functions f(x)andΦ(φ),we have introduced the notationsG(0)[Φ(φ),f(x)]=Φ2(φ)f′2(x)+Φ′2(φ)f2(x)/x2+2Φ2(φ)f2(x),(28)G(1)[Φ(φ),f(x)]=−Φ2(φ)f′2(x)−Φ′2(φ)f2(x)/x2.(29) As we see the parts in the VEVs induced by the cylindrical shell are symmetric with respect to the half-planeφ=φ0/2.The expression in the right-hand side of(27)isfinite for0<r<a including the points on the wedge sides,and diverges on the shell.Tofind the leading term in the corresponding asymptotic expansion,we note that near the shell the main contribution comes from large values of m.By using the uniform asymptotic expansions of the modified Bessel functions(see,for instance,[43]) for large values of the order,up to the leading order,for the points a−r≪a|sinφ|,a|sin(φ0−φ)| wefindF2 cyl≈−3(−1)ηF1πa4 r I1(x).(31) In this case the quantity B2 cyl takes afinite limiting value on the edge r=0,whereas E2 cyl vanishes as r2.For q<1+ηF1the main contribution comes form the mode with m=1and the shell-induced parts diverge on the edge r=0.The leading terms are given by the formulaF2 cyl≈−(−1)ηF1q(r/a)2(q−1)Iq(x)−K′q(x)3Vacuum energy-momentum tensor inside the cylindrical shell Now let us consider the VEV of the energy-momentum tensor in the region inside the cylindrical shell.Substituting the eigenfunctions(2)intothecorresponding mode-sum formula,for the non-zero components we obtain (no summation over i )0|T i i |0 =q4π2a∂2π2∞ ′m =0 λ=0,1 ∞0dxx 3K (λ)qm (xa )4π2∂I (λ)qm (xa )I 2qm (xr ),(39)with the notations F (i )[Φ(φ),f (y )]=Φ2(φ)f 2(y ),i =0,3,(40)F (i )[Φ(φ),f (y )]=−(−1)i Φ2(φ)f ′2(y )− Φ2(φ)−(−1)i Φ′2(φ)/y2 f 2(y ),i =1,2.(41)The diagonal components are symmetric with respect to the half-plane φ=φ0/2,whereas the off-diagonal component is an odd function under the replacement φ→φ0−φ.As it can be easily checked,the tensor T k i cyl is traceless and satisfies the covariant continuity equation ∇k T k i cyl =0.For the geometry under consideration the latter leads to the relations∂∂φT 22 cyl =0,(42)∂∂φ T 21 cyl = T 22 cyl .(43)As it is seen from formula(39),the off-diagonal component T12 cyl vanishes at the wedge sides and for these points the VEV of the energy-momentum tensor is diagonal.By using the in-equalities I′ν(x)< 1+ν2/x2Kν(x)for the modified Bessel functions,it can be seen that K′ν(x)/I′ν(x)+Kν(x)/Iν(x)<0.From this relation it follows that the vacuum energy density induced by the cylindrical shell in the interior region is always negative.The renormalized VEV of the energy-momentum tensor for the geometry without the cylin-drical shell is obtained by using the corresponding formulae for thefield square.For the corre-sponding energy density onefindsT00 w,ren=1720π2r4.(44) As we see the parts in the VEVs of thefield square which diverge on the wedge sides cancel out and the corresponding energy density isfinite everywhere except the edge.Formula(44) coincides with the corresponding result for the geometry of the cosmic string(see[44,45])with the angle deficit2π−φ0and in the corresponding formula q=2π/φ0.Other components are found from the tracelessness condition and the continuity equation and one has[29,30](see also [2])T k i w,ren=−(q2−1)(q2+11)240π2r4,(47) is the normal force acting per unit surface of the wedge for the case without a cylindrical boundary and the additional termp2cyl=− T22 cyl|φ=0,φ0=−qI(λ)qm(xa)F(λ)qm[I qm(xr)],(48)with the notationF(λ)ν[f(y)]= ν2f2(y)/y2,λ=0−f′2(y)−f2(y),λ=1,(49)is induced by the cylindrical shell.From formula(47)we see that the corresponding vacuum forces are attractive for q>1and repulsive for q<1.In particular,the equilibrium position corresponding to the geometry of a single plate(q=1)is unstable.As regards to the part induced by the cylindrical shell,from(48)it follows that p2cyl<0and,hence,the corresponding forces are always attractive.Now,let us discuss the behavior of the boundary-induced part in the VEV of the energy-momentum tensor in the asymptotic region of the parameters.Near the cylindrical shell the main contribution comes from large values of m.Thus,using the uniform asymptotic expansionsfor the modified Bessel functions for large values of the order,up to the leading order,for the points a −r ≪a |sin φ|,a |sin(φ0−φ)|we findT 00 cyl ≈−160π2a , T 11 cyl ≈(a −r )−24π2a 4 ∞0dx x 3K ′0(x )a 4,i =0,3.(51)For the components (no summation over i ) T i i cyl ,i =1,2,when q >1the main contributionagain comes form m =0term and one has T i i cyl ≈− T 00 cyl ,i =1,2.For q <1the main contribution into the components T i i cyl ,i =1,2,comes from the term m =1and we have (nosummation over i )T i i cyl ≈(−1)i q cos(2qφ)a 2(q −1) ∞0dx x 2q +1 K q (x )I ′q(x ) ,i =1,2.(52)In this case the radial and azimuthal stresses induced by the cylindrical shell diverge on the edge r =0.In the case q =1the sum of the contributions of the terms with m =0and m =1given by formulae(51)and (52)should be taken.For the off-diagonal component the main contribution comes from the m =1mode with the leading termT 12 cyl ≈q sin(2qφ)a 2q −1 ∞0dx x 2q +1 K q (x )I ′q(x ) ,(53)and this component vanishes on the edge for q >1/2.In the limit q ≫1,the contribution of the modes with m 1is suppressed by the factor exp[−2qm ln(a/r )]and the main contribution comes from the m =0mode.The leading terms are given by the formulae (no summation over i )T i i cyl ≈q I ′0(x )I 20(xr/a ),i =0,3,(54)T i i cyl ≈−qI ′0(x ) I 20(xr/a )+(−1)i I 21(xr/a ),i =1,2.(55)Though in this limit the vacuum densities are large,due to the factor 1/q in the spatial volume,the corresponding global quantities tend to finite value.In particular,as it follows from Eq.(55),in the limit under consideration one has T i i cyl >0.Note that in the same limit the parts corresponding to the wedge without the cylindrical shell behave as q 4and,hence,for points not too close to the shell these parts dominate in the VEVs.In figures 2-5we have plotted the parts in the VEVs of the energy-momentum tensor induced by the cylindrical shell,a 4 T k i cyl ,as functions of x =(r/a )cos φand y =(r/a )sin φ,for a wedge with the opening angle φ0=π/2.In figure 6we have presented the dependence of the effective azimuthal pressure induced by the cylindrical shell on the wedge sides,a 4p 2cyl ,as a function of r/a for different values of the parameter q .--0a 4<T 00>cylFigure 2:The part in the VEV of the

cylindrical shell on the wedge sides,a 4p 2cyl ,as a function of r/a .The numbers near the curves correspond to the values of the parameter q .There are several special cases of interest for the geometry of boundaries we have consid-ered.The case φ0=πcorresponds to the semi-circular cylinder.The Casimir energy for the corresponding interior region is evaluated in Ref.[34]by using the zeta function technique.The case φ0=2πcorresponds to the geometry of a cylindrical shell with a coaxial half-plane.And finally,the limit φ0→0,r,a →∞,assuming that a −r and aφ0≡b are fixed,corresponds to the geometry of two parallel plates separated by a distance b ,perpendicularly intersected by the third plate.In the latter case it is convenient to introduce rectangular coordinates (x ′1,x ′2,x ′3)=(x,y,z )with the relations x =a −r ,y =rφ.The components of the tensors in these coordinates we will denote by primes.The corresponding vacuum energy-momentum tensor is presented in the form0|T ′i k |0 = T ′i k (0)+ T ′i k (1),(56)where T ′i k (0)is the vacuum expectation value in the region between two parallel plates located at y =0and y =a and T ′i k (1)is induced by the intersecting plate at x =0.The latter is related to the quantities investigated above by formulaeT ′i i (1)=lim T i i cyl , T ′12 (1)=−lim 1for the vector potential are obtained from formulae (2)bythereplacement J qm (γr )→g (λ)qm (γa,γr )=J qm (γr )Y (λ)qm (γa )−Y qm (γr )J (λ)qm (γa ),(58)where,as before,λ=0,1correspond to the waves of the electric and magnetic types,respec-tively.Now,the eigenvalues for γare continuous and in the normalization condition (4)the corresponding part on the right is presented by the delta function.As the normalization inte-gral diverges for γ′=γ,the main contribution into the integral comes from large values of r and we can replace the cylindrical functions with the argument γr by their asymptotic expressions for large values of the argument.By this way it can be seen that the normalization coefficient in the exterior region is determined by the relationβ−2α=8ππ∞ ′m =0 +∞−∞dk ∞0dγ λ=0,1γ3k 2+γ2g (ηF λ)[Φ(λ)qm (φ),g (λ)qm (γa,γr )]J (λ)2qm (γa )+Y (λ)2qm (γa )=g (ηF λ)[Φ(λ)qm (φ),J qm (γr )]−1H (s )(λ)qm (γa )g (ηF λ)[Φ(λ)qm (φ),H (s )qm (γr )],(61)where H (1,2)qm (z )are the Hankel functions.In order to transform the integral over γwith the last term on the right of (61),in the complex plane γwe rotate the integration contour by the angle π/2for the term with s =1and by the angle −π/2for the term with s =2.Due to the well-known properties of the Hankel functions the integrals over the corresponding parts of the circles of large radius in the upper and lower half-planes vanish.After introducing the modified Bessel functions and integrating over k with the help of formula (26),we can write the VEVs of the field square in the form (13),where the part induced by the cylindrical shell is given by the formulaF 2 cyl =2q K (λ)qm (xa )G (ηF λ)[Φ(λ)qm (φ),K qm (xr )].(62)In this formula the functions G (ηF λ)[Φ(φ),f (x )]are defined by formulae (28),(29).Comparing this result with formula (27),we see that the expressions for the shell-induced parts in the interior and exterior regions are related by the interchange I qm ⇄K qm .The VEV (62)diverges on the cylindrical shell with the leading term being the same as that for the interior region.At large distances from the cylindrical shell we introduce a new integration variable y =xr andexpand the integrand over a/r .For q >1the main contribution comes from the lowest mode m =0and up to the leading order we haveE 2 cyl ≈4q r 2, B 2 cyl ≈−28q r2.(63)For q <1the dominant contribution into the VEVs at large distances is due to the mode m =1with the leading termF 2 cyl ≈−4q 2(q +1)r 2q cos(2qφ)2q +1.(64)For the case q =1the contributions of the modes m =0and m =1are of the same order and the corresponding leading terms are obtained by summing these contributions.The latter are given by the right-hand sides of formulae (63)and (64).As we see,at large distances the part induced by the cylindrical shell is suppressed with respect to the part corresponding to the wedge without the shell by the factor (a/r )2βwith β=min(1,q ).Now we turn to the VEVs of the energy-momentum tensor in the exterior region.Substi-tuting the eigenfunctions into the corresponding mode-sum formula,one finds (no summation over i )0|T i i |0 =q J (λ)2qm (γa )+Y (λ)2qm (γa ),(65) 0|T 12|0 =−q∂r ∞ ′m =0m sin(2qmφ)+∞−∞dk ∞0dγ λ=0,1(−1)λγg (λ)2qm (γa,γr )k 2+γ2.(66)Subtracting from these VEVs the corresponding expression for the wedge without the cylindrical boundary,analogously to the case of the field square,it can be seen that the VEVs are presented in the form (37),with the parts induced by the cylindrical shell given by the formulae (no summation over i )T i i cyl =q K (λ)qm (xa )F (i )[Φ(λ)qm (φ),K qm (xr )],(67) T 12 cyl =q 2∂r ∞ ′m =0m sin(2qmφ) λ=0,1(−1)λ ∞0dxx I (λ)qm (xa )π2∞ ′m =0 λ=0,1 ∞0dxx 3I (λ)qm (xa )The leading divergence in the boundary induced part(67)on the cylindrical surface is given by the same formulae as for the interior region.For large distances from the shell and for q >1the main contribution into the VEVs of the diagonal components comes from the m =0,λ=1term and one has (no summation over i )T i i cyl ≈−qc ir 2,c 0=c 3=2,c 1=1,c 2=−5.(70)In the case q <1the main contribution into the VEVs of the diagonal components at large distances from the cylindrical shell comes from the m =1mode.The leading terms in the corresponding asymptotic expansions are given by the formulaeT i i cyl≈−q 2(q +1)c i (q )cos(2qφ)r 2q ,(71)with the notationsc 0(q )=c 3(q )=1(2q +1)(2q +3),c 2(q )=−q +12q +1sin(2qφ)r 2q .(73)For large values of q ,q ≫1,the contribution of the terms with m >0is suppressed by the factor exp[−2qm ln(r/a )]and the main contribution comes form the m =0term with the behavior F 2 cyl ∝q and T k i cyl ∝q .In figure 7we have
