Radiative processes of single and entangled detectors on circular trajectories in ($2+1$)-dimensional Minkowski spacetime

|
By Subhajit Barman, Bibhas Ranjan Majhi, L. Sriramkumar
| Physical Review B
We investigate the radiative processes involving two entangled Unruh-DeWitt detectors that are moving on circular trajectories in (2+1)-dimensional Minkowski spacetime. We assume that the detectors are coupled to a massless, quantum scalar field, and calculate the transition probability rates of the detectors in the Minkowski vacuum as well as in a thermal bath.

Universal role of curvature in vacuum entanglement

|
By Subhajit Barman, Dawood Kothawala
| Physical Review B
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 state. The probes are initially causally disconnected and nonentangled. We explore the parameter space {ω,d0,v0} spanned by the energy gap ω of the detectors, and the initial values of separation distance d0 and relative velocity v0, both covariantly defined in arbitrary curved spacetime.
