Electromagnetic Casimir densities induced by a conducting cylindrical shell in the cosmic string spacetime
arXiv:hep-th/0611310 · doi:10.1016/j.physletb.2006.12.052
Abstract
We investigate the renormalized vacuum expectation values of the field square and the energy-momentum tensor for the electromagnetic field inside and outside of a conducting cylindrical shell in the cosmic string spacetime. By using the generalized Abel-Plana formula, the vacuum expectation values are presented in the form of the sum of boundary-free and boundary-induced parts. The asymptotic behavior of the vacuum expectation values of the field square, energy density and stresses are investigated in various limiting cases.
