Fitting NANOGrav 15-year data and ACT data with modified inflation in entropic cosmology

Simone D'Onofrio, Sergei Odintsov, Tanmoy Paul

Recent evidences of stochastic gravitational wave background (SGWB) through Pulsar Time Array (PTA) observations hint towards an alternative inflationary scenario, compared to the…

ACT inflation and its influence on reheating era in Einstein-Gauss-Bonnet gravity

Sergei D. Odintsov, Tanmoy Paul

We investigate the observational viability of non-minimally coupled scalar-Einstein-Gauss-Bonnet (GB) gravity, during inflation and post-inflationary reheating dynamics, from the p…

Generalized entropic dark energy with spatial curvature

Sergei D. Odintsov, Simone D'Onofrio, Tanmoy Paul

In the realm of thermodynamics of apparent horizon, we construct a dark energy (DE) model from 4-parameter generalized entropy of apparent horizon in a spatially non-flat universe.…

Origin of bulk viscosity in cosmology and its thermodynamic implications

Tanmoy Paul

The purpose of the present work is two folded: (1) we propose a new mechanism for the origin of bulk viscosity in cosmological context, and then, (2) we address the thermodynamic i…

Modified gravity as entropic cosmology

Shin'ichi Nojiri, Sergei D. Odintsov, Tanmoy Paul +1

The present work reveals a direct correspondence between modified theories of gravity (cosmology) and entropic cosmology based on the thermodynamics of apparent horizon. It turns o…

Different aspects of entropic cosmology

Shin'ichi Nojiri, Sergei D. Odintsov, Tanmoy Paul

We give a short review of the recent developments of entropic cosmology based on two thermodynamic laws of the apparent horizon, namely the first and the second laws of thermodynam…

Natural validation of the second law of thermodynamics in cosmology

Sergei D. Odintsov, Tanmoy Paul, Soumitra SenGupta

The present work shows that the second law of thermodynamics gets naturally satisfied during the entire cosmic evolution of the universe starting from inflation to the late dark en…

Primordial gravitational waves in horizon cosmology and constraints on entropic parameters

Sergei D. Odintsov, Simone D'Onofrio, Tanmoy Paul

The hallmark of the 4-parameter generalized entropy is that it can represent various known entropies proposed so far for suitable limits of the parameters, and thus the 4-parameter…

Second law of horizon thermodynamics during cosmic evolution

Sergei D. Odintsov, Tanmoy Paul, Soumitra SenGupta

We examine the second law of thermodynamics in the context of horizon cosmology, in particular, whether the change of total entropy (i.e. the sum of the entropy for the apparent ho…

Cosmology of unimodular Born-Infeld- gravity

Salih Kibaroğlu, Sergei D. Odintsov, Tanmoy Paul

We propose a novel modified gravity: unimodular generalization of the Born-Infeld- gravity within the framework of cosmology. After formulating the action corresponding to th…

f(R) gravity with spacetime torsion

Hitender Kumar, Tanmoy Paul, Soumitra SenGupta

The duality between a higher curvature gravity model and a scalar-tensor theory helps to bring out the role of the additional degree of freedom originating from the higher d…

Entropic Inflation in Presence of Scalar Field

Sergei D. Odintsov, Simone D'Onofrio, Tanmoy Paul

In spirit of the recently proposed four-parameter generalized entropy of apparent horizon, we investigate inflationary cosmology where the matter field inside of the horizon is dom…

Microscopic interpretation of generalized entropy

Shin'ichi Nojiri, Sergei D. Odintsov, Tanmoy Paul

Generalized entropy, that has been recently proposed, puts all the known and apparently different entropies like The Tsallis, the Rényi, the Barrow, the Kaniadakis, the Sharma-Mitt…
