Bounce, Turnaround, and the Anisotropy Problem in Cyclic Cosmology on a Brane with a Timelike Extra Dimension
Rikpratik Sengupta, Arkajit Aich, Kaushik Bhattacharya
We study cosmological bounces, turnarounds, and cyclic evolution on an anisotropic Bianchi-I brane embedded in a five-dimensional bulk with a \emph{timelike} extra dimension, withi…

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…
