Entropy spectrum of BTZ black hole in massive gravity

TL;DR

This paper investigates the quantization of entropy in (2+1) BTZ black holes within massive gravity models, demonstrating that their entropy spectra are equally spaced using a formalism based on adiabaticity and horizon oscillations.

Contribution

It introduces a novel application of the Jiang and Han formalism to massive gravity, showing that BTZ black hole entropy spectra are quantized with equal spacing.

Findings

Entropy spectra are quantized with equal spacing.

The formalism effectively describes black hole entropy quantization in massive gravity.

Supports the idea of discrete black hole entropy in lower-dimensional gravity models.

Abstract

We study the entropy spectrum of (2+1) BTZ black holes in massive gravity models. We use the formalism proposed by Jiang and Han where black hole property of adiabaticity and the oscillating velocity of the black hole horizon are used to investigate the quantization of the entropy of such systems. We find that the entropy of the BTZ black holes in massive gravity is quantized with equally spaced spectra.
