Is warm inflation quasi-stable?
Akash Bose, Subenoy Chakraborty
The present work deals with a non-equilibrium thermodynamics that is associated with the scenario of warm inflation. The premise is that an adiabatic radiation production process h…
Static spherically symmetric wormhole with quadratic shape function and particle trajectories around it
Bikram Ghosh, Sourav Dutta, Sudeshna Mukerji +1
The paper deals with static traversable wormhole having shape function a polynomial of the radial coordinate of degree 2. Embedding of the wormholes in space-time is examined both…
Some specific wormhole solutions in -modified gravity theory
Bikram Ghosh, Saugata Mitra, Subenoy Chakraborty
The paper deals with the static spherically symmetric wormhole solutions in -modified gravity theory with anisotropic matter field and for some particular choices for the sha…
String cosmology in Bianchi I space-time
A. Banerjee, Abhik Kumar Sanyal, S. Chakraborty
Some cosmological solutions of massive strings are obtained in Bianchi I space-time following the techniques used by Letelier and Stachel. A class of solutions corresponds to strin…
Bianchi II, VIII, and IX viscous fluid cosmology
A. Banerjee, Abhik Kumar Sanyal, S. Chakraborty
In this paper we study the exact solutions for a viscous fluid distribution in Bianchi II, VIII, and IX models. The metric is simplified by assuming a relationship between the coef…
Quantum cosmology with symmetry analysis for quintom dark energy model
Sourav Dutta, Muthusamy Lakshmanan, Subenoy Chakraborty
Quantum cosmology with quintom dark energy model has been investigated in the present work using symmetry analysis of the underlying physical system. In the background of the flat…
