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…
Multicritical Phase Transitions in Lovelock AdS Black Holes
Jerry Wu, Robert B. Mann
We demonstrate that black holes in order Lovelock gravity can exhibit multicritical phase behaviour. We show an explicit example of a quadruple point in fourth-orde…
Mutual information harvested by uniformly accelerated particle detectors
Manar Naeem, Kensuke Gallock-Yoshimura, Robert B. Mann
We investigate the mutual information harvesting protocol for two uniformly accelerated particle detectors. We numerically show that, while a single detector responds as if it is i…
Universality for Black Hole Heat Engines Near Critical Points
Maria C. DiMarco, Sierra L. Jess, Robie A. Hennigar +1
Johnson has shown [arXiv:1703.06119] that in the vicinity of a critical point the efficiency of a black hole heat engine can approach the Carnot efficiency while maintaining finite…
Locally detecting UV cutoffs on a sphere with particle detectors
Ahmed Shalabi, Laura J. Henderson, Robert B. Mann
The potential breakdown of the notion of a metric at high energy scales could imply the existence of a fundamental minimal length scale below which distances cannot be resolved. On…
On the Lagrangian Holographic Relation at and Limits of Gravity
H. Khodabakhshi, H. Lu, R. B. Mann
The gravitational Lagrangian can be written as a summation of a bulk and a total derivative term. For some theories of gravity such as Einstein gravity, or more general Lovelock gr…
Distinguishing a Slowly Accelerating Black Hole by Differential Time Delays of Images
Amjad Ashoorioon, Mohammad Bagher Jahani Poshteh, Robert B. Mann
Accelerating supermassive black holes, connected to cosmic strings, could contribute to structure formation and get captured by galaxies if their velocities are small. This would m…
Slowly Rotating Black Holes in 4D Einstein Gauss-Bonnet Gravity
Michael Gammon, Robert Mann
Since the recent derivation of a well-defined limit for regularized 4D Einstein Gauss-Bonnet (4DEGB) gravity, there has been considerable interest in testing it as…
Quantum superpositions of Minkowski spacetime
Joshua Foo, Cemile Senem Arabaci, Magdalena Zych +1
Within any anticipated unifying theory of quantum gravity, it should be meaningful to combine the fundamental notions of quantum superposition and spacetime to obtain so-called "sp…
Black Hole Solutions as Topological Thermodynamic Defects
Shao-Wen Wei, Yu-Xiao Liu, Robert B. Mann
In this work, employing the generalized off-shell free energy, we treat black hole solutions as defects in the thermodynamic parameter space. The results show that the positive and…
Multicritical Phase Transitions in Multiply Rotating Black Holes
Jerry Wu, Robert B. Mann
We show that multi-critical points in which more than three phases coalesce are present in multiply rotating Kerr-AdS black holes in -dimensions. We explicitly present a quadrup…
Negative Mass Black Holes in de-Sitter Space
Brayden R. Hull, Robert B. Mann
We show that asymptotically de Sitter black holes of negative mass can exist in Lovelock gravity. Such black holes have horizon geometries with non-constant curvature and are known…
Vortex/anti-vortex pair creation in black hole thermodynamics
Moaathe Belhaj Ahmed, David Kubiznak, Robert B. Mann
An isolated critical point is a peculiar thermodynamic critical point that occurs in the phase diagram of hyperbolic black holes in Kth-order Lovelock gravity in higher dimensions…
Fisher Information of a Black Hole Spacetime
Everett Patterson, Robert B. Mann
Relativistic quantum metrology is the study of optimal measurement procedures within systems that have both quantum and relativistic components. Here we use Unruh-DeWitt detectors…
Multi-critical Points in Black Hole Phase Transitions
Masoumeh Tavakoli, Jerry Wu, Robert B. Mann
We present the first examples in black hole thermodynamics of multicritical phase transitions, in which more than three distinct black hole phases merge at a critical point. Workin…
Entanglement harvesting of three Unruh-DeWitt detectors
Diana Mendez-Avalos, Laura J. Henderson, Kensuke Gallock-Yoshimura +1
We analyze a tripartite entanglement harvesting protocol with three Unruh-DeWitt detectors adiabatically interacting with a quantum scalar field. We consider linear, equilateral tr…
Stellar representation of extremal Wigner-negative spin states
Jack Davis, Robie Hennigar, Robert B. Mann +1
The Majorana stellar representation is used to characterize spin states that have a maximally negative Wigner quasiprobability distribution on a spherical phase space. These maxima…
Entanglement Harvesting of Inertially Moving Unruh-DeWitt Detectors in Minkowski Spacetime
Cendikiawan Suryaatmadja, Wan Cong, Robert . B. Mann
We investigate the effects of relative motion on entanglement harvesting by considering a pair of Unruh-Dewitt detectors moving at arbitrary, but independent and constant velocitie…
Harvesting mutual information from BTZ black hole spacetime
Kendra Bueley, Luosi Huang, Kensuke Gallock-Yoshimura +1
We investigate the correlation harvesting protocol for mutual information between two Unruh-DeWitt detectors in a static BTZ black hole spacetime. Here, the effects coming from com…
Instant Extraction of Non-Perturbative Tripartite Entanglement
Diana Méndez Avalos, Kensuke Gallock-Yoshimura, Laura J. Henderson +1
We consider the problem of extracting tripartite entanglement through single local instantaneous interactions of a separable target system A-B-C with a scalar field. We find, non-p…
Schrödinger's Black Hole Cat
Joshua Foo, Robert B. Mann, Magdalena Zych
In the absence of a fully-fledged theory of quantum gravity, we propose a "bottom-up" framework for exploring quantum-gravitational physics by pairing two of the most fundamental c…
Unruh-DeWitt detector in dimensionally-reduced static spherically symmetric spacetimes
Erickson Tjoa, Robert B. Mann
We study the dynamics of an Unruh-DeWitt detector interacting with a massless scalar field in an arbitrary static spherically symmetric spacetimes whose metric is characterised by…
Generalized Lense--Thirring metrics: higher-curvature corrections and solutions with matter
Finnian Gray, Robie A. Hennigar, David Kubiznak +2
The Lense--Thirring spacetime describes a 4-dimensional slowly rotating approximate solution of vacuum Einstein equations valid to a linear order in rotation parameter. It is fully…
Entanglement Harvesting with a Twist
Laura J. Henderson, Su Yu Ding, Robert B. Mann
One consequence of the cosmic censorship conjecture is that any topological structure will ultimately collapse to within the horizons of a set of black holes, and as a result, an e…
