### Comments on the anti-Hawking effect on a BTZ black hole spacetime

- Physics

The quantum vacuum has long been known to be characterized by field correlations between spacetime points. We show that such correlations—vacuum entanglement—in the environment of near-extremal black…

Abstract
We study the harvesting of correlations by two Unruh-DeWitt static detectors from the vacuum state of a massless scalar field in a background Vaidya spacetime consisting of a collapsing null…

We investigate the entanglement dynamics for a quantum system composed of two uniformly accelerated Unruh-DeWitt detectors in diﬀerent spacetime dimensions. It is found that the range of parameters…

### Harvesting mutual information from BTZ black hole spacetime

- Computer Science, PhysicsPhysical Review D
- 2022

It is found that, unlike the entanglement harvesting scenario, harvested mutual information is zero only when a detector reaches an event horizon, and that although the Hawking e-ect and gravitational redshift both a-ect the extraction of mutual information, it is extreme Hawking radiation that inhibits the detectors from harvesting.

### Unruh-DeWitt detectors in cosmological spacetimes

- PhysicsPhysical Review D

We analyse the response and thermal behaviour of an Unruh-DeWitt detector as it travels through cosmological spacetimes, with special reference to the question of how to deﬁne surface gravity and…

We consider the response of an Unruh-DeWitt detector near an extremal charged black hole, modeling the near-horizon region of this extremal spacetime by the Bertotti-Robinson spacetime. The advantage…

### Anti-Hawking phenomena around a rotating BTZ black hole

- PhysicsPhysical Review D
- 2022

In both ﬂat and curved spacetimes, there are weak and strong versions of the anti-Unruh/anti-Hawking eﬀects, in which the KMS ﬁeld temperature is anti-correlated with the response of a detector and…
