Non-linear density-velocity dynamics in gravity from spherical collapse
Sharvari Nadkarni-Ghosh, Sandip Chowdhury
We investigate the joint density-velocity evolution in gravity using smooth, compensated spherical top-hats as a proxy for the non-linear regime. Using the Hu-Sawicki model…
Disformal transformations and the motion of a particle in semi-classical gravity
Sandip Chowdhury, Kunal Pal, Kuntal Pal +1
The approach to incorporate quantum effects in gravity by replacing free particle geodesics with Bohmian non-geodesic trajectories has an equivalent description in terms of a confo…
Quantum potential in dust collapse with a negative cosmological constant
Sandip Chowdhury, Kunal Pal, Kuntal Pal +1
In the functional Schrodinger formalism, we obtain the wave function describing collapsing dust in an anti-de Sitter background, as seen by a co-moving observer, by mapping the res…
Collapse in gravity and the method of matching
Sandip Chowdhury, Kunal Pal, Kuntal Pal +1
Collapsing solutions in gravity are restricted due to junction conditions that demand continuity of the Ricci scalar and its normal derivative across the time-like collapsin…
Zitterbewegung of a heavy hole in presence of spin-orbit interactions
Tutul Biswas, Sandip Chowdhury, Tarun Kanti Ghosh
We study the of a heavy hole in presence of both cubic Rashba and cubic Dresselhaus spin-orbit interactions. On contrary to the electronic case, d…
