Infrared Corrections and Horizon Phase Transitions in Kaniadakis-Based Holographic Dark Energy
Manuel Gonzalez-Espinoza, Samuel Lepe, Joel F. Saavedra +1
We study the cosmological and thermodynamic implications of holographic dark energy derived from the Kaniadakis deformation of the Bekenstein-Hawking entropy. Within a spatially fl…
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…
Revealing some cosmological aspects of Kaniadakis entropy
Miguel Cruz, Samuel Lepe, Joel Saavedra
Adopting the modifications induced by the truncated version of the Kaniadakis entropy on the Friedmann equations, we explore some relevant aspects of this cosmological scenario at…
Matter creation, adiabaticity and phantom behavior
VÃctor H. Cárdenas, Samuel Lepe
We present a novel cosmological framework that unifies matter creation dynamics with thermodynamic principles. Starting with a single-component fluid characterized by a constant eq…
