Empty Black Holes, Firewalls, and the Origin of Bekenstein-Hawking Entropy
Mehdi Saravani, Niayesh Afshordi, Robert B. Mann
We propose a novel solution for the endpoint of gravitational collapse, in which spacetime ends (and is orbifolded) at a microscopic distance from black hole event horizons. This m…
Detectors for probing relativistic quantum physics beyond perturbation theory
Eric G. Brown, Eduardo Martin-Martinez, Nicolas C. Menicucci +1
We develop a general formalism for a non-perturbative treatment of harmonic-oscillator particle detectors in relativistic quantum field theory using continuous-variables techniques…
Holographic Renormalization of Asymptotically Flat Gravity
Miok Park, Robert B. Mann
We compute the boundary stress tensor associated with Mann-Marolf counterterm in asymptotic flat and static spacetime for cylindrical boundary surface as , an…
Is wave-particle objectivity compatible with determinism and locality?
Radu Ionicioiu, Thomas Jennewein, Robert B. Mann +1
Wave-particle duality, superposition and entanglement are among the most counterintuitive features of quantum theory. Their clash with our classical expectations motivated hidden-v…
Eguchi-Hanson like space-times in F(R) gravity
S. H. Hendi, R. B. Mann, N. Riazi +1
We consider a model of gravity in which exponential and power corrections to Einstein- gravity are included. We show that this model has 4-dimensional Eguchi-Hanson type…
Singularities in Hyperscaling Violating Spacetimes
Keith Copsey, Robert Mann
We examine spacetimes which generalize Lifshitz scaling to allow hyperscaling violation invariance (i.e. a constant conformal transformation) for the types of singularities frequen…
A Soliton and a Black Hole are in Gauss-Bonnet gravity. Who wins?
Anson W. C. Wong, Robert B. Mann
We study here the phase-transitional evolution between the Eguchi-Hanson soliton, the orbifolded Schwarzschild Anti de-Sitter black hole, and orbifolded thermal Anti de-Sitter spac…
Entanglement and discord: accelerated observations of local and global modes
Jason Doukas, Eric G. Brown, Andrzej Dragan +1
We investigate the amount of entanglement and quantum discord extractable from a two mode squeezed state as considered from the viewpoint of two observers, Alice (inertial) and Rob…
Extended phase space thermodynamics for charged and rotating black holes and Born-Infeld vacuum polarization
Sharmila Gunasekaran, David Kubiznak, Robert B. Mann
We investigate the critical behaviour of charged and rotating AdS black holes in d spacetime dimensions, including effects from non-linear electrodynamics via the Born-Infeld actio…
Quantum state cloning in the presence of a closed timelike curve
D. Ahn, C. R. Myers, T. C. Ralph +1
The possible existence of closed timelike curves (CTCs) draws attention to fundamental questions about what is physically possible and what is not. An example is the "no cloning th…
Quasi-topological Reissner-Nordström Black Holes
W. G. Brenna, R. B. Mann
We consider Reissner-Nordstrom solutions in quasi-topological gravity, obtaining exact solutions to the field equations yielding charged quasi-topological black holes. We study the…
Quasilocal Conservation Laws: Why We Need Them
Paul L. McGrath, Richard J. Epp, Robert B. Mann
We argue that conservation laws based on the local matter-only stress-energy-momentum tensor (characterized by energy and momentum per unit volume) cannot adequately explain a wide…
Fundamental quantum optics experiments conceivable with satellites -- reaching relativistic distances and velocities
David Rideout, Thomas Jennewein, Giovanni Amelino-Camelia +14
Physical theories are developed to describe phenomena in particular regimes, and generally are valid only within a limited range of scales. For example, general relativity provides…
Vanishing Geometric Discord in Non-Inertial Frames
Eric G. Brown, Kyle Cormier, Eduardo Martin-Martinez +1
We show that quantum field correlations in non-inertial frames are not as persistent as previously thought. We perform a simple calculation showing that the geometric discord, a me…
P-V criticality of charged AdS black holes
David Kubiznak, Robert B. Mann
Treating the cosmological constant as a thermodynamic pressure and its conjugate quantity as a thermodynamic volume, we reconsider the critical behaviour of charged AdS black holes…
Another Mass Gap in the BTZ Geometry?
Sean Stotyn, Robert B. Mann
We attempt the construction of perturbative rotating hairy black holes and boson stars, invariant under a single helical Killing field, in 2+1-dimensions to complete the perturbati…
Deformations of Lifshitz Holography in -dimensions
Miok Park, Robert B. Mann
We investigate deformations of Lifshitz holography in dimensional spacetime. After discussing the situation for general Lifshitz scaling symmetry parameter , we consider…
