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…
Can spacetime fluctuations generate entanglement between co-moving accelerated detectors?
Dipankar Barman, Bibhas Ranjan Majhi
Recent studies [Class. Quant. Grav. 42, 03LT01 (2025); Phys. Rev. D 111, 045023 (2025)] indicate that in a nested sequence of Rindler wedges, vacuum of former Rindler frame appears…
Mirror-enhanced acceleration-induced geometric phase
Dipankar Barman, Debasish Ghosh, Bibhas Ranjan Majhi
Fulling-Davies-Unruh effect contains great amount of theoretical importance in various branches of physics. Requirement of very high acceleration hinders its experimental evidence.…
Role of thermal field in entanglement harvesting between two accelerated Unruh-DeWitt detectors
Dipankar Barman, Subhajit Barman, Bibhas Ranjan Majhi
We investigate the effects of field temperature on the entanglement harvesting between two uniformly accelerated detectors. For their parallel motion, the thermal nature…
