Vacuum polarization in a cosmic string spacetime induced by flat boundary
arXiv:1106.2450 · doi:10.1142/S201019451100095X
Abstract
In this paper we analyze the vacuum expectation values of the field squared and the energy-momentum tensor associated to a massive scalar field in a higher dimensional cosmic string spacetime, obeying Dirichlet or Neumann boundary conditions on the surface orthogonal to the string.
