Equivalence in virtual transitions between uniformly accelerated and static atoms: from a bird's eye
Pradeep Kumar Kumawat, Subhajit Barman, Bibhas Ranjan Majhi
We study the prospect of the equivalence principle at the quantum regime by investigating the transition probabilities of a two-level atomic detector in different scenarios. In par…
Pure Gauss-Bonnet NUT Black Hole Solution: II
Sajal Mukherjee, Subhajit Barman
In the present article, we have obtained an exact analytical solution of six-dimensional pure Gauss-Bonnet gravity in the presence of both NUT and Maxwell charges. The topology of…
Timelike transitions in an atom by a mirror in light cone and Kruskal-Szekeres regions: a status of quantum equivalence
Subhajit Barman, Pradeep Kumar Kumawat, Bibhas Ranjan Majhi
We investigate the timelike transitions in a two-level atom in the presence of an infinite reflecting mirror in the future-past light cone regions of a Minkowski spacetime, as well…
Signatures of gravitational wave memory in the radiative process of entangled quantum probes
Subhajit Barman, Indranil Chakraborty, Sajal Mukherjee
In this article, we examine entangled quantum probes in geodesic trajectories in a flat background with a gravitational wave (GW) burst. In particular, these quantum probes are pre…
