The logotropic dark fluid as an energy diffusion in unimodular gravity
Miguel Cruz, Samuel Lepe
We show that the logotropic dark fluid, proposed as a single-fluid unification of dark matter and dark energy, is exactly dissipative unimodular gravity with pressureless matter an…
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 Criticality in FLRW Cosmology with Non-extensive Loop Quantum Gravity Entropy
Miguel Cruz, Joel Saavedra, Juan Rodriguez
We investigate thermodynamic criticality in a spatially flat Friedmann-Lema\^ıtre-Robertson-Walker universe with a non-extensive Loop Quantum Gravity inspired entropy on its appare…
Curvature-induced phantom behavior and cosmological bounces without violating the Dominant Energy Condition
Miguel Cruz, Samuel Lepe
We show that a spatially closed universe can exhibit effective phantom dynamics () and reach a finite-time cosmological event without violating the Dominant Energy Condition…
Cosmological Stealth fields and Non-Equilibrium thermodynamics
Gilberto Aguilar-Pérez, Cuauhtemoc Campuzano, Víctor H. Cárdenas +2
We investigate the connection between cosmological stealth scalar fields and non-equilibrium thermodynamics in a spatially flat Friedmann-Lemaître-Robertson-Walker (FLRW) backgroun…
Spatial curvature in Unimodular Gravity
Gilberto Aguilar-Pérez, Miguel Cruz, Samuel Lepe
We investigate the cosmological implications of unimodular gravity (UG) featuring energy diffusion and spatial curvature. While standard diffusion models often suffer from thermody…
