Holographic CFT Phase Transitions and Criticality for Charged AdS Black Holes
Wan Cong, David Kubiznak, Robert Mann +1
We study the hololgraphic dual of the extended thermodynamics of spherically symmetric, charged AdS black holes in the context of the AdS/CFT correspondence. The gravitational ther…
Black holes and their horizons in semiclassical and modified theories of gravity
Robert B. Mann, Sebastian Murk, Daniel R. Terno
For distant observers black holes are trapped spacetime domains bounded by apparent horizons. We review properties of the near-horizon geometry emphasizing the consequences of two…
Quantum signatures of black hole mass superpositions
Joshua Foo, Cemile Senem Arabaci, Magdalena Zych +1
We present a new operational framework for studying ``superpositions of spacetimes'', which are of fundamental interest in the development of a theory of quantum gravity. Our appro…
Does acceleration assist entanglement harvesting?
Zhihong Liu, Jialin Zhang, Robert B. Mann +1
We explore whether acceleration assists entanglement harvesting for a pair of uniformly accelerated detectors in three different acceleration scenarios, i.e., parallel, anti-parall…
Lensing Signatures of a Slowly-Accelerated Black Hole
Amjad Ashoorioon, Mohammad Bagher Jahani Poshteh, Robert B. Mann
Accelerating black holes, connected to cosmic strings could evolve to supermassive black holes. However, if they are going to take part in structure formation and resides at the ce…
Reentrant phase transitions in Einstein-Maxwell-scalar black holes
Dumitru Astefanesei, Paulina Cabrera, Robert B. Mann +1
We consider how scalar fields affect the thermodynamic behavior of charged anti-de Sitter (AdS) black holes. We specifically investigate a class of (3+1)-dimensional exact hairy ch…
Paradoxes before the paradox: surface gravity and the information loss problem
Robert B. Mann, Sebastian Murk, Daniel R. Terno
The information loss paradox is widely regarded as one of the biggest open problems in theoretical physics. Several classical and quantum features must be present to enable its for…
A Little Excitement Across the Horizon
Keith K. Ng, Chen Zhang, Jorma Louko +1
We analyse numerically the transitions in an Unruh-DeWitt detector, coupled linearly to a massless scalar field, in radial infall in (3+1)-dimensional Schwarzschild spacetime. In t…
Entangled Detectors Nonperturbatively Harvest Mutual Information
Kensuke Gallock-Yoshimura, Robert B. Mann
We investigate how entangled inertial Unruh-DeWitt detectors are affected by interaction with a quantum field using a nonperturbative method. Inertial detectors in a -dimens…
Characteristic interaction potential of black hole molecules from the microscopic interpretation of Ruppeiner geometry
Shao-Wen Wei, Yu-Xiao Liu, Robert B. Mann
Ruppeiner geometry has been found to be a novel promising approach to uncover the microstructure of fluid systems and black holes. In this work, combining with the micro model of t…
Phase Transitions in 4D Gauss-Bonnet-de Sitter Black Holes
Gareth Arturo Marks, Fil Simovic, Robert B. Mann
We investigate thermodynamic aspects of black holes in the recently formulated four dimensional Gauss-Bonnet theory of gravity, focusing on its asymptotically de Sitter () sol…
Stellar Structure and Stability of Charged Interacting Quark Stars and Their Scaling Behaviour
Chen Zhang, Michael Gammon, Robert B. Mann
We explore the stellar structure and radial stability of charged quark stars composed of interacting quark matter (IQM) in three classes of commonly used charge models. We adopt a…
Thermodynamics of Dyonic NUT Charged Black Holes with Entropy as Noether Charge
Niloofar Abbasvandi, Masoumeh Tavakoli, Robert B. Mann
We investigate the thermodynamic behaviour of Lorentzian Dyonic Taub-NUT Black Hole spacetimes. We consider two possibilities in their description: one in which their entropy is in…
Anti-Hawking Phenomena around a Rotating BTZ Black Hole
Matthew P. G. Robbins, Robert B. Mann
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 respon…
