Universal Entropy Bound for Rotating Systems

TL;DR

This paper proposes a universal entropy bound for rotating systems, derived from the generalized second law of thermodynamics, which is stricter than the Bekenstein bound for non-rotating systems.

Contribution

It introduces a new universal entropy bound applicable to rotating systems, extending the Bekenstein bound through a gedanken experiment involving black holes.

Findings

Derived a stronger entropy bound for rotating systems.

Applied the generalized second law to a thought experiment.

Established the bound's universality for rotating objects.

Abstract

We conjecture a universal upper bound to the entropy of a rotating system. The entropy bound follows from application of the generalized second law of thermodynamics to an idealized gedanken experiment in which an entropy-bearing rotating system falls into a black hole. This bound is stronger than the Bekenstein entropy bound for non-rotating systems.
