Spinning test particles in the spacetime of a global monopole
Morteza Mohseni, Saurya Das
We investigate the motion of spinning test particles in the spacetime of a global monopole in the framework of the Mathisson-Papapetrou-Dixon equations. By making use of the symmet…
Quantum resolution of the Schwarzschild singularity
Vishnulal Cheriyodathillathu, Tanmay Patil, Saurya Das +1
We revisit the Schwarzschild singularity in a semiclassical setting where the background geometry is classical and quantum effects enter through Bohmian (quantal) trajectories asso…
Closing the Cosmographic Hierarchy: Dynamical Attractors from Inflation to Reheating
Seturumane Tema, S. Shajidul Haque, Saurya Das +1
We develop a potential-independent cosmographic framework, in which cosmographic parameters are promoted to dynamical variables within a closed autonomous system. Although the cosm…
Interaction of exact gravitational waves with matter
Morteza Mohseni, Saurya Das
We consider interactions of exact (i.e., solutions of full nonlinear field equations) gravitational waves with matter by using the Einstein-Boltzmann equation. For a gravitational…
Power-Law Bounces in Gravity: Analysis of the Ekpyrosis and Accelerating Regimes
Saurya Das, Peter Dunsby, S. Shajidul Haque +1
We investigate the dynamics of the Friedmann-Lemaître-Robertson-Walker spacetime within the framework of gravity using a compact, model-independent dynamical systems approac…
Superradiance of anyons
Vishnulal Cheriyodathillathu, Saurya Das, Soumen Basak
In this paper, we investigate superradiance of anyons from a (2+1)-dimensional Bañados, Teitelboim and Zanelli (BTZ) black hole. Our analysis demonstrates that the superradiance co…
Cosmological Singularity and Power-Law Solutions in Modified Gravity
Saurya Das, S. Shajidul Haque, Seturumane Tema
A bouncing Universe avoids the big-bang singularity. Using the time-like and null Raychaudhhuri equations, we explore whether the bounce near the big-bang, within a broad spectrum…
