Detector's response to coherent Rindler and Minkowski photons
Pradeep Kumar Kumawat, Dipankar Barman, Bibhas Ranjan Majhi
We observe that the transition probability in a static two-level quantum detector interacting with a coherent Rindler field mode differs from that of the Rindler detector interacti…

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…

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…
