Entanglement harvesting from conformal vacuums between two Unruh-DeWitt detectors moving along null paths
Subhajit Barman, Dipankar Barman, Bibhas Ranjan Majhi
It is well-known that the dimensional Schwarzschild and spatially flat FLRW spacetimes are conformally flat. This work examines entanglement harvesting from the conformal f…
Hawking effect in an extremal Kerr black hole spacetime
Saumya Ghosh, Subhajit Barman
It is well known that extremal black holes do not Hawking radiate, which is usually realized by taking an extremal limit from the nonextremal case. However, one cannot perceive the…
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…
Radiative process of two entangled uniformly accelerated atoms in a thermal bath: a possible case of anti-Unruh event
Subhajit Barman, Bibhas Ranjan Majhi
We study the radiative process of two entangled two-level atoms uniformly accelerated in a thermal bath, coupled to a massless scalar field. First, using the positive frequency Wig…
Thermal behavior of a radially deformed black hole spacetime
Subhajit Barman, Sajal Mukherjee
In the present article, we study the Hawking effect and the bounds on greybody factor in a spacetime with radial deformation. This deformation is expected to carry the imprint of a…
