Harvesting mutual information from BTZ black hole spacetime

K Bueley, L Huang, K Gallock-Yoshimura, RB Mann - Physical Review D, 2022 - APS
We investigate the correlation harvesting protocol for mutual information between two Unruh-
DeWitt detectors in a static Bañados-Teitelboim-Zanelli black hole spacetime. Here, the …

More excitement across the horizon

MR Preciado-Rivas, M Naeem, RB Mann, J Louko - Physical Review D, 2024 - APS
An Unruh-DeWitt detector falling radially into a four-dimensional Schwarzschild black hole,
coupled linearly to a massless scalar field that has been prepared in the Hartle-Hawking or …

[HTML][HTML] Quantum kicks near a Cauchy horizon

BA Juárez-Aubry, J Louko - AVS Quantum Science, 2022 - pubs.aip.org
We analyze a quantum observer who falls geodesically toward the Cauchy horizon of a (1+
1)-dimensional eternal black hole spacetime with the global structure of the non-extremal …

Singular excitement beyond the horizon of a rotating black hole

S Wang, MR Preciado-Rivas, M Spadafora, RB Mann - Physical Review D, 2024 - APS
Previous studies have shown that an Unruh-DeWitt (UDW) detector, when coupled linearly
to a massless scalar field and permitted to fall radially into certain black holes, will exhibit …

Unruh-DeWitt detectors in cosmological spacetimes

A Conroy - Physical Review D, 2022 - APS
We analyze the response and thermal behavior of an Unruh-DeWitt detector as it travels
through cosmological spacetimes, with special reference to the question of how to define …

Conditions for anti-Unruh effect

D Wu, J Yang, Y Shi - The European Physical Journal C, 2023 - Springer
Conditions for anti-Unruh effect in (1+ 1)-dimensional spacetime are obtained. For detectors
with Gaussian switching functions, the analytical results are similar to previous ones …

Virtual transitions in an atom-mirror system in the presence of two scalar photons

A Das, S Sen, S Gangopadhyay - Physical Review D, 2023 - APS
We examine the virtual transition of an atom-mirror system with the simultaneous emission of
two scalar photons, where the atom and the mirror admit a relative acceleration between …

Probing thermal effects on static spacetimes with Unruh-DeWitt detectors

LDS Campos - arXiv preprint arXiv:2203.09976, 2022 - arxiv.org
In the lack of a full-fledged theory of quantum gravity, I consider free, scalar, quantum fields
on curved spacetimes to gain insight into the interaction between quantum and gravitational …

[HTML][HTML] Boundary conditions and infrared divergences

L de Souza Campos, C Dappiaggi, L Sinibaldi - Physics Letters B, 2024 - Elsevier
We review the procedure to construct quasi-free ground states, for real scalar fields whose
dynamics is dictated by the Klein-Gordon equation, on standard static Lorentzian manifolds …

Exact conditions for antiUnruh effect in (1+ 1)-dimensional spacetime

D Wu, J Yang, Y Shi - arXiv preprint arXiv:2305.11453, 2023 - arxiv.org
