Abstract

We will study the physical effects due to the arbitrariness on the choice of the boundary conditions at the spatial boundary in non-globally-hyperbolic spaces. Our aim is to analyse how is the bath of particles that one observer in a particular vacuum (corresponding to a particular bondary condition) receives from another vacuum (cor- responding to a different boundary condition). We expect to find an analogue of Unruh effect in this case.
