Analytic detector responses and entanglement in constant-curvature spacetimes
Dyuman Bhattacharya, Jiayue Yang, Ming Zhang +1
We derive analytic response functions for Unruh--DeWitt detectors coupled to real, massless, conformally coupled scalar fields, to distinguish the effects of the field spectrum and…

Probing hidden topology with quantum detectors
Dyuman Bhattacharya, Jorma Louko, Robert B. Mann
We consider the transition rate of a static Unruh-DeWitt detector in two -dimensional black hole spacetimes that are isometric to the static Bañados-Teitelboim-Zanelli black…
