Quantum speed limit time of a uniformly accelerated Unruh-DeWitt detector
Debasish Ghosh, Bibhas Ranjan Majhi
Within the open quantum system formalism, using the Markovian process, we investigate the {\it quantum speed limit time} (QSLT) of a uniformly accelerated Unruh-DeWitt detector, in…

Influence of thermal bath on Pancharatnam-Berry phase in an accelerated frame
Debasish Ghosh, Bibhas Ranjan Majhi
A uniformly accelerated atom captures Pancharatnam-Berry phase in its quantum state and the phase factor depends on the vacuum fluctuation of the background quantum fields. We obse…

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.…
