Quasi-homogeneous geometrothermodynamics of a noncommutative Reissner-Nordstrom black hole
Alberto Maya, Hernando Quevedo
We present the thermodynamic properties of a noncommutative Reissner Nordstrom (NCRN) black hole (BH) modeled with Lorentzian distributions. The analysis is carried out using a Leg…
Quasi-Homogeneous Thermodynamics and Microscopic Structure of the Quantum-Corrected FLRW Universe
Carlos E. Romero-Figueroa, Hernando Quevedo
The analysis of phase transitions in cosmological spacetimes shows that their existence requires a time-dependent apparent horizon radius, which in turn implies an equation of stat…
Temperature definitions and phase transitions within non-minimal large and small inflationary potentials
Jesus Anaya-Galeana, Orlando Luongo, Hernando Quevedo
We explore and compare two distinct temperature definitions for scalar field inflation in the context of small- and large-field potentials. The first is based on a real gas, fluid-…
Thermodynamics of the FLRW apparent horizon in Einstein-Gauss-Bonnet gravity
Luis M. Sánchez, Hernando Quevedo
We analyze the thermodynamic properties of the apparent horizon of Friedmann-Lemaître-Roberson-Walker (FLRW) spacetimes in Einstein-Gauss-Bonnet gravity. We use the generalized def…
Constraining quadrupole deformations with relativistic effects
Daniya Utepova, Kuantay Boshkayev, Serzhan Momynov +4
We investigate two general relativistic effects - namely, the Shirokov and Shapiro effects - within the framework of the Zipoy-Voorhees spacetime (-metric), which generalizes th…
Non-extensive and quasi-homogeneous geometrothermodynamics
Hernando Quevedo, María N. Quevedo
We study the thermodynamic properties of black holes, taking into account the non-extensive character of their entropy at the thermodynamic and statistical level. To this end, we a…
