Matter Creation in Unimodular Gravity Cosmology
Víctor H. Cárdenas, Miguel Cruz, Samuel Lepe
We investigate matter creation in the cosmological framework of unimodular gravity. We keep the energy density , pressure , particle number density , and particle number $…
Thermodynamic behavior of cosmological models with fractional entropy
Miguel Cruz, Diego da Silva, Simón González +3
We investigate the thermodynamic and phenomenological implications of a cosmological model governed by fractional entropy applied to the apparent horizon of a flat Friedmann-Lemaît…
Classical emergence of the quantum-backreacted BTZ black hole from exponential electrodynamics
Julio A. Méndez-Zavaleta, Efraín Rojas, José Joaquín Suárez-Garibay
In this work, we revisit a recently reported generalization of the Bañados-Teitelboim-Zanelli black hole arising in New Massive Gravity sourced by the quantum fluctuations of scala…
The holographic origin of future singularities and the role of spatial curvature in cosmic expansion
Miguel Cruz, Samuel Lepe, Joel Saavedra
We investigate the fundamental cosmological implications of holographic dark energy using the Granda-Oliveros (GO) infrared cutoff, spatial curvature, and generalized entropies. We…
Interacting Generalized Chaplygin-Jacobi gas: Thermodynamics approach
Gilberto Aguilar-Pérez, Miguel Cruz, Mohsen Fathi +1
This work investigates a cosmological model featuring an interaction between dark energy and dark matter, where the dark energy component is described by the Generalized Chaplygin-…
First-order phase transitions and cosmic evolution: thermodynamic approach to generalized holographic dark energy
Miguel Cruz, Joaquin Housset, Samuel Lepe +2
Focusing on the description of cosmic evolution at late times, this study examines a generalized holographic dark energy (HDE) framework constructed via a polynomial expansion in t…
