Stimulated emission of particles by 1+1 dimensional black holes

TL;DR

This paper investigates how black holes in 1+1 dimensions stimulate emission of particles, analyzing the thermal and non-thermal radiation properties for different scalar fields and states near the horizon.

Contribution

It provides a comparative study of stimulated emission in relativistic and CGHS black holes, highlighting their thermal and non-thermal radiation characteristics.

Findings

Radiation exhibits both thermal and non-thermal features.

Stimulated emission depends on the initial particle and thermal states.

Differences observed between relativistic and CGHS black hole models.

Abstract

The stimulated emission of massless bosons by a relativistic and the CGHS black hole are studied for real and complex scalar fields. The radiations induced by one-particle and thermal states are considered and their thermal properties investigated near the horizon. These exhibit both thermal and non-thermal properties for the two black-hole models.
