Emission of Fermions from BTZ Black Holes

TL;DR

This paper demonstrates that fermion emission rates from BTZ black holes can be derived from conformal field theory and are consistent with rates from higher-dimensional black holes with BTZ near-horizon geometry.

Contribution

It establishes a connection between fermion emission from 2+1D BTZ black holes and conformal field theory, also relating it to higher-dimensional black hole emissions.

Findings

Fermion emission rate matches conformal field theory predictions.

Emission rate is identical to that from five-dimensional black holes with BTZ near-horizon geometry.

Provides a link between lower-dimensional black hole physics and higher-dimensional models.

Abstract

The emission rate of fermions from 2+1 dimensional BTZ black holes is shown to have a form which can be reproduced from a conformal field theory at finite temperature. The rate obtained for fermions is identical to the rate of non-minimally coupled fermions emitted from a five dimensional black hole, whose near horizon geometry is BTZ X M, where M is a compact manifold.
