This study explores the link between modified gravity and modifications of phase space
volume. Analyzing Fermi gas modifications in the nonrelativistic limit of the Ricci-based …

Fermi gas and modified gravity

A Wojnar - Physical Review D, 2023 - APS
We derive the equations of state of Fermi gas by maximizing the Fermi-Dirac entropy in
modified gravity in the relativistic and nonrelativistic case. It will be demonstrated that the …

Metric-affine effects in crystallization processes of white dwarfs

S Kalita, L Sarmah, A Wojnar - Physical Review D, 2023 - APS
We analyze the effects of modified gravity on specific heats of electrons and ions, Debye
temperature, crystallization process, and cooling mechanism in white dwarfs. We derive the …

Bose-Einstein condensate and liquid : Implications of the GUP and modified gravity correspondence

A Wojnar - Physical Review D, 2024 - APS
Utilizing the recently established connection between Palatini-like gravity and linear
generalized uncertainty principle (GUP) models, we have formulated an approach that …

How the Schwarzschild–de Sitter horizons remain in thermal equilibrium at vastly different temperatures

M Miranda, M Rinaldi, V Faraoni - Physical Review D, 2024 - APS
The Tolman–Ehrenfest criterion of thermal equilibrium for a static fluid in a static spacetime
is generalized to stationary heat conduction, in the approximation in which backreaction is …

Impact of modified gravity theory on neutron star and nuclear matter properties

N Alam, S Pal, A Rahmansyah, A Sulaksono - Physical Review D, 2024 - APS
New observational data measured with high degree of accuracy of compact isolated neutron

Transport coefficients of dense nucleon matter at low temperature

J Li, W Ke - arXiv preprint arXiv:2412.20454, 2024 - arxiv.org
Transport properties of cold and dense nucleon matter are important for both nuclear and
astrophysics but are relatively less studied than those at finite temperatures. In this paper …

Reconstruction of QCD first-order phase transition from neutron star measurements

R Li, S Han, Z Lin, L Wang, K Zhou, S Shi - arXiv preprint arXiv …, 2025 - arxiv.org
The potential hadron-to-quark phase transition in neutron stars has not been fully
understood as the property of cold, dense, and strongly interacting matter cannot be …

The Tolman-Ehrenfest criterion of thermal equilibrium in scalar-tensor gravity

N Karolinski, V Faraoni - arXiv preprint arXiv:2406.09251, 2024 - arxiv.org
The Tolman-Ehrenfest criterion for the thermal equilibrium of a fluid at rest in a static general-
relativistic geometry is generalized to scalar-tensor gravity. The gravitational scalar field …
