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…
Cosmological Correlations in Power Law Inflation models
Amit Kundu, Prasenjit Paul
Scalar field with non-minimal coupling to curvature scalar is studied in Robertson-Walker background. The infrared limit of two point function, and, in turn, of the energy-momentum…
