Non-singular flat universes in braneworld and Loop Quantum Cosmology
Rikpratik Sengupta, B. C. Paul, M. Kalam +2
In this paper we take matter source with non-linear Equation of state (EoS) that has produced non-singular Emergent cosmology for spatially flat universe in General Relativity and…
Weyl transformation: a dynamical degree of freedom in the light of Dirac's Large Number Hypothesis
Prasenjit Paul, Rikpratik Sengupta, Saibal Ray
In Einstein's Field Equation(EFE) the geometry of the space-time is connected with the matter distribution. The geometry or the gravitational sector deals with classical macroscopi…
Modified Power law Inflation: solution to the graceful exit problem and improvement of dark energy models
Prasenjit Paul, Rikpratik Sengupta, Saibal Ray
We study power law inflation (PLI) with a monomial potential and find a novel exact solution. It is well known that conventional PLI with exponential potential is inconsistent with…
Skyrme Fluid in Anisotropic Universe
Rikpratik Sengupta, B C Paul, Prasenjit Pal
Cosmological solutions are obtained in an anisotropic Kantowski-Sachs (KS) and Bianchi Type-I universes considering a cosmological constant with Skyrme fluid. Interestingly, the so…
Inflation in anisotropic brane universe using tachyon field
Rikpratik Sengupta, Prasenjit Paul, Bikash Chandra Paul +1
Cosmological solution to the gravitational field equations in the generalized Randall-Sundrum model for an anisotropic brane with Bianchi I geometry and perfect fluid as matter sou…
Generalized phenomenological models of dark energy
Prasenjit Paul, Rikpratik Sengupta
It was first observed at the end of the last century that the universe is presently accelerating. Ever since, there have been several attempts to explain this observation theoretic…
