First quantum correction to entropy of Vaidya-Bonner black holes due to arbitrary spin fields

, 2002
Using the improved brick-wall model, we have calculated the first quantum correction to the entropy of non-static black holes, Vaidya-Bonner black holes, due to the gravitational, electro-magnetic and neutrino fields.

Gravitational Algebras and Applications to Nonequilibrium Physics

Universe
This note aims to offer a non-technical and self-contained introduction to gravitational algebras and their applications in the nonequilibrium physics of gravitational systems. We begin by presenting foundational concepts from operator algebra theory and

Trivial Entropy of Matter in Gravitation

, 2020
Expanding the black hole thermodynamics from the horizon to achronal Cauchy hypersurface, the general relation between the Einstein equation and thermodynamics is established. Starting from trivial entropy that is generalized by Bekenstein-Hawking entropy, the entropic mass of matter emerges naturally together with Unruh temperature.

Comments on entanglement entropy in the c = 1 string theory

Journal of High Energy Physics
We study entanglement entropy in the low-energy effective field theory of two-dimensional string theory as well as in the singlet sector of the dual c = 1 matrix quantum mechanics. From the target space perspective, we argue that a generic bulk subregion

Modified Landauer Principle According to Tsallis Entropy

Entropy
The Landauer principle establishes a lower bound in the amount of energy that should be dissipated in the erasure of one bit of information. The specific value of this dissipated energy is tightly related to the definition of entropy. In this article, we

Contextual Gravity: An Entropy-Dependent Modification of the Gravitational Constant

A new theory of gravity where the gravitational constant depends inversely on entropy. Derived from a covariant action, this framework naturally explains cosmic inflation, black hole evaporation, and removes singularities — all without needing a scalar ...

Formulation and proof of the gravitational entropy bound

Journal of High Energy Physics
A bstract We provide a formulation and proof of the gravitational entropy bound. We use a recently given framework which expresses the measurable quantities of a quantum theory as a weighted sum over paths in the theory’s phase space. If this framework is
