Abstract

By gluing together two sections of flat space-time in different metric representations (with the Minkowski metric representing the region far away from the black hole and the Rindler metric modeling the vicinity of the horizon), we construct a simplified toy model for black-hole evaporation. The simple structure of this toy model allows us to construct exact analytic solutions for the two-point functions in the various vacuum states (Israel-Harte-Hawking, Unruh and Boulware states) in an easy way and thus helps to understand and disentangle the different ingredients for Hawking radiation better.
