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…
Finite stress-tensor moment tomography of boundary-graviton coherences
Dyuman Bhattacharya, Robert B. Mann
Einstein gravity in 2+1 dimensions is a topological theory that does not admit the existence of local bulk gravitons. However, gravity with Brown-Henneaux boundary…
Probing holographic conformal field theories
Ming Zhang, Jiayue Yang, Dyuman Bhattacharya +1
We embed relativistic quantum information protocols in AdS/CFT: an Unruh-DeWitt detector coupled to a local primary of a holographic CFT has a reduced state fixed by the universal…
Analytic Tools for Harvesting Magic Resource in Curved Spacetime
Jiayue Yang, Dyuman Bhattacharya, Ming Zhang +1
The quantum vacuum is not really empty; it is a reservoir of operationally accessible non-classical resources. Understanding how to extract these resources to fuel information proc…
Charged rotating quantum black holes
Dyuman Bhattacharya, Robie A. Hennigar, Robert B. Mann +1
We investigate the thermodynamic and holographic properties of charged and rotating quantum black holes in a doubly holographic braneworld setup. These quantum black holes are deri…
Finite-cutoff Holographic Thermodynamics
Ming Zhang, Wen-Di Tan, Mengqi Lu +3
We develop a framework for holographic thermodynamics in finite-cutoff holography, extending the anti-de Sitter/conformal field theory (AdS/CFT) correspondence to incorporate a fin…
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…
Extraction of entanglement from quantum fields with entangled particle detectors
Dyuman Bhattacharya, Kensuke Gallock-Yoshimura, Laura J. Henderson +1
We consider two initially entangled Unruh-DeWitt particle detectors and examine how the initial entanglement changes after interacting with a quantum scalar field. As initially non…
