Thermodynamics of Photon Gas with an Invariant Energy Scale
Sudipta Das, Dibakar Roychowdhury
Quantum Gravity framework motivates us to find new theories in which an observer independent finite energy upper bound (preferably Planck Energy) exists. We have studied the modifi…
Relativistic Thermodynamics with an Invariant Energy Scale
Sudipta Das, Subir Ghosh, Dibakar Roychowdhury
A particular framework for Quantum Gravity is the Doubly Special Relativity (DSR) formalism that introduces a new observer independent scale, the Planck energy. Our aim in this pap…
Emergent Universe Scenario in the Einstein-Gauss-Bonnet Gravity with Dilaton
B C Paul, S Ghose
We obtain cosmological solutions which admit emergent universe (EU) scenario in the framework of Einstein Gauss-Bonnet gravity coupled with a dilaton field in four dimensions. The…
Primordial Black Hole Pair Creation Probability in Modified Gravitational Theory
B. C. Paul, Dilip Paul
The probability for quantum creation of an inflationary universe with a pair of black holes is computed in a modified gravitational theory. Considering a gravitational action which…
Power Law Inflation and the Cosmic No Hair Theorem in Brane World
B. C. Paul, A. Beesham
The Cosmic no hair theorem is studied in anisotropic Bianchi brane models which admit power law inflation with a scalar field. We note that all Bianchi models except Bianchi type I…
A Note on Inflation with Tachyon Rolling on the Gauss-Bonnet Brane
B. C. Paul, M. Sami
In this paper we study the tachyonic inflation in brane world cosmology with Gauss-Bonnet term in the bulk. We obtain the exact solution of slow roll equations in case of exponenti…
