Lorentzian wormhole in the framework of loop quantum cosmology
Rikpratik Sengupta, Shounak Ghosh, Mehedi Kalam
In this paper, we construct a traversable static Lorentzian wormhole in the effective scenario of Loop Quantum Cosmology (LQC), where the field equations are modified due to the ul…
Traversable Lorentzian wormhole on the Shtanov-Sahni braneworld with matter obeying the energy conditions
Rikpratik Sengupta, Shounak Ghosh, M. Kalam
In this paper we have explored the possibility of constructing a traversable wormhole on the Shtanov-Sahni braneworld with a timelike extra dimension. We find that the Weyl curvatu…
Lorentzian wormholes in an emergent universe
Rikpratik Sengupta, Shounak Ghosh, B C Paul +1
A non-singular Emergent Universe (EU) scenario within the realm of standard Relativistic physics requires a generalization of the Equation of State (EoS) connecting the pressure an…
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…
