TL;DR
This paper investigates the semiclassical evolution of a self-gravitating thick shell in Anti-de Sitter space-time, focusing on quantum matter effects and energy radiation, revealing unique emission phenomena compared to flat space.
Contribution
It introduces a model of a quantized bosonic shell in AdS space and analyzes back-reaction effects, highlighting novel emission behavior at large shell radii.
Findings
Emission occurs even for large shell radii in AdS, unlike flat space.
Back-reaction of radiated energy affects shell evolution.
Quantum effects influence gravitational collapse dynamics.
Abstract
We study the semiclassical evolution of a self-gravitating thick shell in Anti-de Sitter space-time. We treat the matter on the shell as made of quantized bosons and evaluate the back-reaction of the loss of gravitational energy which is radiated away as a non-adiabatic effect. A peculiar feature of anti-de Sitter is that such an emission also occurs for large shell radius, contrary to the asymptotically flat case.
