Ideal Gas Thermodynamics with an Invariant Energy Scale
Sudipta Das
A viable approach towards Quantum Gravity is the Doubly Special Relativity (DSR) framework in which an observer-independent finite energy upper bound (or a finite smallest length s…
Perturbation in an interacting dark universe
Srijita Sinha, Manisha Banerjee, Sudipta Das
In this paper we have considered an interacting model of dark energy and have looked into the evolution of the dark sectors. By solving the perturbation equations numerically, we h…
Barrow Holographic Dark Energy in non-flat Universe
Priyanka Adhikary, Sudipta Das, Spyros Basilakos +1
We construct Barrow holographic dark energy in the case of non-flat universe. In particular, considering closed and open spatial geometry we extract the differential equations that…
Growth of Perturbations using Lambert Equation of State
Manisha Banerjee, Sudipta Das, Abdulla Al Mamon +2
Recently, a novel equation of state (EoS) parameter for dark energy has been introduced which deals with a special mathematical function, known as the Lambert function. In this…
Dynamical System Analysis for Steep Potentials
Sudipta Das, Manisha Banerjee, Nandan Roy
In this work we have performed the dynamical system analysis for steep(er) exponential potentials considering different values of the steepness index . We have performed the ana…
A new parametrization of dark energy equation of state leading to double exponential potential
Sudipta Das, Abdulla Al Mamon, Manisha Banerjee
We show that a canonical scalar field with a phenomenological form of energy density or equivalently an equation of state parameter can provide the required transition from deceler…
