Boltzmann Entropy, the Holographic Bound and Newtonian Cosmology
Proceedings, 2017 The holographic principle sets an upper bound on the total (Boltzmann) entropy content of the Universe at around 10 123 k B ( k B being Boltzmann’s constant).

On generalized gravitational entropy, squashed cones and holography [PDF]
, 2014 We consider generalized gravitational entropy in various higher derivative theories of gravity dual to four dimensional CFTs using the recently proposed regularization of squashed cones.

Gravitational entropy of Kerr black holes [PDF]
, 2021 Classical invariants of General Relativity can be used to approximate the entropy of the gravitational field. In this work, we study two proposed estimators based on scalars constructed out from the Weyl tensor, in Kerr spacetime.

Entanglement entropy of gravitational edge modes
Journal of High Energy Physics, 2022 We consider the linearised graviton in 4d Minkowski space and decompose it into tensor spherical harmonics and fix the gauge. The Gauss law of gravity implies that certain radial components of the Riemann tensor of the graviton on the sphere labels the ...

Vacuum energy density and gravitational entropy
Physical Review D, 2023 The failure to calculate the vacuum energy is a central problem in theoretical physics. Presumably the problem arises from the insistent use of effective field theory reasoning in a context that is well beyond its intended scope. If one follows this path, one is led inevitably to statistical or anthropic reasoning for observations.

Black hole entropy and models [PDF]
, 1997 No universally accepted statistical explanation of black hole entropy exists up to now, therefore, it is worth another try. Admittedly, black hole entropy does not have to have a statistical origin. If the "black hole entropy" is called "black hole index"

Gravity is not an entropic force
Physics Letters BVerlinde’s proposal that gravity arises as an entropic force is re-examined through two carefully constructed thermodynamic processes involving a gravitational field.

Charge conservation, entropy current and gravitation
International Journal of Modern Physics A, 2021 We propose a new class of vector fields to construct a conserved charge in a general field theory whose energy–momentum tensor is covariantly conserved. We show that there always exists such a vector field in a given field theory even without global symmetry.
