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 $…
Does spatial curvature generate new thermodynamic criticality at the FLRW apparent horizon?
Samuel Lepe, Joel Saavedra
We generalize the apparent-horizon thermodynamic construction of [1] to a FLRW universe with non-zero spatial curvature, non-interacting cold dark matter and holographic-type dark…
Kaniadakis Holographic Dark Energy: UVIR Duality, Horizon Thermodynamics and Cosmological Constraints
Manuel Gonzalez-Espinoza, Samuel Lepe, Joel F. Saavedra +1
We investigate the cosmological and thermodynamic implications of holographic dark energy derived from the Kaniadakis deformation of the Bekenstein--Hawking entropy. In a spatially…
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…
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…
