Quasiparticle picture of black holes and the entropy--area relation

TL;DR

This paper models 0-brane black holes as a gas of non-interacting quasiparticles to explain their thermodynamic and dynamic properties, including the entropy-area relation, within a dual quantum mechanics framework.

Contribution

It introduces a quasiparticle-based effective model for black holes that captures static and dynamic properties, linking entropy to horizon area.

Findings

Entropy proportional to horizon area in Planck units

Model reproduces black hole thermodynamics

Explains energy thermalization rate

Abstract

We propose an effective description of 0-brane black holes, in which the black hole is modeled as a gas of non-interacting quasi-particles in the dual quantum mechanics. This simple model is shown to account for many of the static thermodynamic properties of the black hole. It also accounts for dynamical properties, such as the rate at which energy gets thermalized by the black hole. We use the model to show that the entropy of the quantum mechanics is proportional to the black hole horizon area in Planck units.
