Correlation harvesting between particle detectors in uniform motion
Lana Bozanic, Manar Naeem, Kensuke Gallock-Yoshimura +1
We investigate the correlation harvesting protocol using two Unruh-DeWitt particle detectors moving along four classes of uniformly accelerated trajectories categorized by Letaw: l…
Triple Points of Gravitational AdS Solitons and Black Holes
Constanza Quijada, Andrés Anabalón, Robert B. Mann +1
We present a triple point of a new kind for General Relativity, at which two gravitational solitons can coexist with a planar black hole in anti de Sitter space. Working in the con…
Quantum Otto engine driven by quantum fields
Kensuke Gallock-Yoshimura, Vaishant Thakur, Robert B. Mann
We consider a quantum Otto engine using an Unruh-DeWitt particle detector model which interacts with a quantum scalar field in curved spacetime. We express a generic condition for…
Vacuum entanglement probes for ultra-cold atom systems
Cisco Gooding, Allison Sachs, Robert B. Mann +1
This study explores the transfer of nonclassical correlations from an ultra-cold atom system to a pair of pulsed laser beams. Through nondestructive local probe measurements, we in…
Black hole solutions to Einstein-Bel-Robinson gravity
S. N. Sajadi, Robert B. Mann, H. Sheikhahmadi +1
In this paper, we study the physical properties of black holes in the framework of the recently proposed Einstien-Bel-Robinson gravity. We show that interestingly the theory propag…
Maxwell construction and multi-criticality in uncharged generalized quasi-topological black Holes
Mengqi Lu, Robert B. Mann
We demonstrate the existence of -tuple critical points of uncharged AdS black holes in generalized quasi-topological theories. The criticality is shown to have a geometrical int…
Holographic CFT Phase Transitions and Criticality for Rotating AdS Black Holes
Moaathe Belhaj Ahmed, Wan Cong, David Kubiznak +2
Employing the novel exact dictionary between the laws of extended black hole thermodynamics and the laws of the dual CFT, we study the extended thermodynamics for CFT states that a…
Extended phase space thermodynamics for hairy black holes
Dumitru Astefanesei, Paulina Cabrera, Robert B. Mann +1
We expand our results in \cite{Astefanesei:2019ehu} to investigate a general class of exact hairy black hole solutions in Einstein-Maxwell-dilaton gravity. The dilaton is endowed w…
Signatures of discretization in quantum black hole spectra
Joshua Foo, Robert B. Mann, Magdalena Zych
The quantum superposition principle states that quantum-mechanical systems such as atoms can be placed in a superposition of mass-energy eigenstates. Inspired by this idea and the…
Polytopes of Absolutely Wigner Bounded Spin States
Jérôme Denis, Jack Davis, Robert B. Mann +1
Quasiprobability has become an increasingly popular notion for characterising non-classicality in quantum information, thermodynamics, and metrology. Two important distributions wi…
Dynamic behaviours of black hole phase transitions near quadruple points
Jiayue Yang, Robert B. Mann
Treating the horizon radius as an order parameter in a thermal fluctuation, the free energy landscape model sheds light on the dynamic behaviour of black hole phase transitions. He…
Tripartite Entanglement Extraction from the Black Hole Vacuum
Ireneo James Membrere, Kensuke Gallock-Yoshimura, Laura J. Henderson +1
The first investigation of tripartite entanglement harvesting in the vicinity of a black hole is carried out. Working in the context of a static Bañados-Teitelboim-Zanelli (BTZ) bl…
Static spheres around spherically symmetric black hole spacetime
Shao-Wen Wei, Yu-Peng Zhang, Yu-Xiao Liu +1
Unique features of particle orbits produce novel signatures of gravitational observable phenomena, and are quite useful in testing compact astrophysical objects in general relativi…
Slowly Rotating Black Holes in Einsteinian Quartic Gravities
Gareth Arturo Marks, Robert B. Mann, Damian Sheppard
We study slowly rotating black hole solutions in the six independent theories of Einstein Quartic Gravity (EQG) in four dimensions. Unlike in the static case for which all six theo…
Holographic dual of extended black hole thermodynamics
Moaathe Belhaj Ahmed, Wan Cong, David Kubizňák +2
By respecting the conformal symmetry of the dual CFT, and treating the conformal factor of the AdS boundary as a thermodynamic parameter, we formulate the holographic first law tha…
Relativity and decoherence of spacetime superpositions
Joshua Foo, Robert B. Mann, Magdalena Zych
It is univocally anticipated that in a theory of quantum gravity, there exist quantum superpositions of semiclassical states of spacetime geometry. Such states could arise for exam…
Phase Transitions and Stability of Eguchi-Hanson-AdS Solitons
Turkuler Durgut, Robie A. Hennigar, Hari K. Kunduri +1
The Eguchi-Hanson-AdS family of spacetimes are a class of static, geodesically complete asymptotically locally AdS soliton solutions of the vacuum Einstein equations with n…
