Cosmological consequences of scale-dependent Barrow-Tsallis entropy
Giuseppe Gaetano Luciano, Orlando Luongo, Marco Muccino
The paper explores a cosmological model with a scale‑dependent Barrow‑Tsallis entropy, deriving modified Friedmann equations and confronting the model with various early‑ and late‑…
Thermodynamic formulation of Cotton gravity in the Codazzi parametrization
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…
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 thermodyna…
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…
Observational constraints on Luciano-Saridakis entropic cosmology
MatÃas 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…
Testing gravitational wave polarizations with LISA
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…
