Barrow holographic dark energy with varying exponent
Spyros Basilakos, Andreas Lymperis, Maria Petronikolou +1
We construct Barrow holographic dark energy with varying exponent. Such an energy-scale-dependent behavior is typical in quantum field theory and quantum gravity under renormalizat…
Modified cosmology though spacetime thermodynamics and generalized mass-to-horizon entropy
Spyros Basilakos, Andreas Lymperis, Maria Petronikolou +1
In this work we apply the gravity-thermodynamics approach for the case of generalized mass-to-horizon entropy, which is a two-parameter extension of Bekenstein-Hawking entropy that…
Correspondence between Myrzakulov gravity and Tsallis cosmology
Andreas Lymperis, Gulgassyl Nugmanova, Almira Sergazina
We investigate the correspondence between Myrzakulov gravity and Tsallis cosmology. The former is a modified gravity that uses both curvature and nonmetricity, while the l…
Non-singular bounce solutions in Myrzakulov gravity
Andreas Lymperis, Gulgassyl Nugmanova, Almira Sergazina
We investigate the realization of a nonsingular bounce within the framework of Myrzakulov \( F(R,T) \) gravity. This modified gravitational theory uses a non-special connection tha…
