Universal role of curvature in vacuum entanglement
Hari K, Subhajit Barman, Dawood Kothawala
We highlight some universal features concerning the role of spacetime curvature in the entanglement induced between quantum probes coupled to a quantum field in a suitable vacuum s…
Entanglement harvesting for different gravitational wave burst profiles with and without memory
Subhajit Barman, Indranil Chakraborty, Sajal Mukherjee
In the present article, we study how different gravitational wave (GW) burst profiles in linearized gravity, with and without the asymptotic memory, may influence the harvesting be…
Optimization of entanglement depends on whether a black hole is extremal
Subhajit Barman, Bibhas Ranjan Majhi
We consider two Unruh-DeWitt detectors interacting with a massless, minimally coupled scalar field in a dimensional Reissner-Nordström black hole spacetime. In particular,…
