Wormholes: Myth or Reality? Prospects for Future Observations
Subenoy Chakraborty, Madhukrishna Chakraborty
Traversable wormholes (TWHs) remain one of the most intriguing predictions of General Relativity (GR), offering passage through space-time. However, their existence requires the vi…
Exploring Traversable Wormholes in gravity: Shadows and Quasinormal modes
Madhukrishna Chakraborty, Subenoy Chakraborty
The present work deals with some WH solutions in gravity theory for non-constant red-shift function subject to a power law model of , being the non-metricity scala…
A study of Raychaudhuri equation and geodesic focusing in Fractal Universe
Madhukrishna Chakraborty, Subenoy Chakraborty
The paper deals with the modified Raychaudhuri equation (RE) within the framework of homogeneous and isotropic Fractal Universe. Focusing of a congruence of time-like geodesics has…
Black Hole singularity and its possible mitigations: Reformulation of Penrose Singularity theorem using null Raychaudhuri matrix
Madhukrishna Chakraborty, Subenoy Chakraborty
In this paper, we introduce a notion of null Raychaudhuri matrix motivated by the matrix representation of tensor fields. The evolution of this matrix gives the matrix form of null…
Raychaudhuri equation and the dynamics of cosmic evolution
Madhukrishna Chakraborty, Subenoy Chakraborty
The paper deals with the Raychaudhuri equation (RE) which is a non-linear ordinary differential equation in , the expansion scalar corresponding to a geodesic flow. Focusing the…
A Revisit to Classical and Quantum aspects of Raychaudhuri equation and possible resolution of Singularity
Subenoy Chakraborty, Madhukrishna Chakraborty
In this review, we provide a concrete overview of the Raychaudhuri equation, Focusing theorem and Convergence conditions in a plethora of backgrounds and discuss the consequences.…
