Entropy applications in cosmology: spacetime thermodynamics, holographic dark energy, entropic gravity and beyond - a review
Emmanuel N. Saridakis, Giuseppe Gaetano Luciano, Andreas Lymperis +1
Entropy has emerged as a key concept at the intersection of gravity, quantum theory, and cosmology, revealing deep connections between geometry, information, and thermodynamics. Th…
Observational constraints on Luciano-Saridakis holographic dark energy
Matías Leizerovich, Susana J. Landau, Giuseppe Gaetano Luciano +2
Holographic dark energy (HDE) models provide a natural framework for linking gravitational thermodynamics to the late-time accelerated expansion of the Universe. In this work, we i…
Cosmological consequences of scale-dependent Barrow-Tsallis entropy
Giuseppe Gaetano Luciano, Orlando Luongo, Marco Muccino
We investigate an extended cosmological scenario based on the Barrow-Tsallis entropy, incorporating a varying (i.e., energy-scale-dependent) anomalous dimension. This behavior is r…
From information bounds to infrared gravity: implications of Sharma-Mittal entropy
Abdelhakim Benkrane, Giuseppe Gaetano Luciano, Ahmad Sheykhi
The Sharma--Mittal (SM) entropy provides a two-parameter generalization encompassing both the Rényi and Tsallis statistical frameworks. In this work, we investigate its thermodynam…
Constraints on Kaniadakis Cosmology from Starobinsky Inflation and Primordial Tensor Perturbations
Abdelhakim Benkrane, Giuseppe Gaetano Luciano
We investigate a generalized entropic cosmology obtained by applying the gravity-thermodynamics conjecture to the Universe horizon using Kaniadakis statistics, namely a relativisti…

Shayesteh Ghaffari, Giuseppe Gaetano Luciano, Carlo Alberto Mantica
We develop a thermodynamic formulation of Cotton gravity in the Codazzi parametrization, providing a general framework in which the gravitational dynamics can be interpreted in ter…

Shingo Akama, Maxence Corman, Paola C. M. Delgado +16
In this paper we quantify the ability of the Laser Interferometer Space Antenna (LISA) to test the presence of non-tensorial polarizations as well as modifications to the tensor on…
Observational constraints on Luciano-Saridakis entropic cosmology
Matías Leizerovich, Susana J. Landau, Giuseppe Gaetano Luciano +2
A recently proposed generalized entropy by Luciano and Saridakis extends the standard Boltzmann-Gibbs and Bekenstein-Hawking framework through a microscopically motivated construct…

In the framework of entropic cosmology, entropic forces arising at the cosmological horizon have been proposed as an alternative mechanism to explain the Universe's current acceler…
Late-Time Cosmological Constraints on Kaniadakis Holographic Dark Energy
Giuseppe Gaetano Luciano, Andronikos Paliathanasis
Kaniadakis Holographic Dark Energy is a one-parameter extension of the standard HDE framework, in which the horizon entropy is reformulated using Kaniadakis entropy. At the cosmolo…
