General form of thermodynamical entropy for black hole

TL;DR

This paper explores a generalized formulation of black hole entropy that extends beyond the traditional area law, even at the semiclassical level, suggesting new insights into black hole thermodynamics.

Contribution

It proposes a generalized form of black hole entropy that differs from the standard area law at the semiclassical level.

Findings

Entropy can deviate from quarter of the area at semiclassical level

New generalized entropy formula proposed for black holes

Implications for black hole thermodynamics and quantum gravity

Abstract

The entropy of a black hole can be different from a quarter of the area even at the semiclassical level.
