Fermionic vacuum polarization by a cylindrical boundary in the cosmic string spacetime

Abstract

The vacuum expectation values of the energy–momentum tensor and the fermionic condensate are analyzed for a massive spinor field obeying the MIT bag boundary condition on a cylindrical shell in the cosmic string spacetime. Both regions inside and outside the shell are considered. By applying to the corresponding mode-sums a variant of the generalized Abel… (More)
