Mach's principle in atomic transitions
Subhajit Barman, Bibhas Ranjan Majhi
We investigate the atomic transition probabilities in atom-mirror set-ups that are in circular motion. In one scenario, the atom is in circular motion inside a static cylindrical m…
Twin-paradox and Entanglement
K. Hari, Subhajit Barman, Dawood Kothawala
We study the quantum version of the classical twin paradox in special relativity by replacing the twins with quantum detectors, and studying the transitions and entanglement induce…
Radiative process of tripartite entangled probes in inertial motion
Subhajit Barman, K. Hari
We study the radiative process of three entangled quantum probes initially prepared in a tripartite W state. As a basic set-up, we consider the probes to be inertial in flat spacet…
Entanglement between accelerated probes in a de Sitter spacetime
Mayank, K. Hari, Subhajit Barman +1
We initiate an investigation into features of vacuum entanglement as probed by accelerated quantum probes in curved spacetime. Focussing specifically on de Sitter (dS) spacetime wi…
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…
