Hamiltonian Formulation of Scalar Field Collapse in Einstein Gauss Bonnet Gravity
T. Taves, C. D. Leonard, G. Kunstatter +1
We compute the Hamiltonian for spherically symmetric scalar field collapse in Einstein-Gauss-Bonnet gravity in D dimensions using slicings that are regular across future horizons.…
Entanglement Dynamics between Inertial and Non-uniformly Accelerated Detectors
David C. M. Ostapchuk, Shih-Yuin Lin, Robert B. Mann +1
We study the time-dependence of quantum entanglement between two Unruh-DeWitt detectors, one at rest in a Minkowski frame, the other non-uniformly accelerated in some specified way…
Gravitational collapse of K-essence Matter in Painlevé-Gullstrand coordinates
C. Danielle Leonard, Jonathan Ziprick, Gabor Kunstatter +1
We conduct numerical simulations in Painlevé-Gullstrand coordinates of a variety of K-essence-type scalar fields under spherically symmetric gravitational collapse. We write down g…
Mass Inflation in the Loop Black Hole
Eric G. Brown, Robert B. Mann, Leonardo Modesto
In classical general relativity the Cauchy horizon within a two-horizon black hole is unstable via a phenomenon known as mass inflation, in which the mass parameter (and the spacet…
Cosmological production of noncommutative black holes
Robert B. Mann, Piero Nicolini
We investigate the pair creation of noncommutative black holes in a background with positive cosmological constant. As a first step we derive the noncommutative geometry inspired S…
