Charged soliton--black hole phase transitions in three-dimensional Einstein--Gauss--Bonnet gravity
Cendikiawan Suryaatmadja, Robert Mann
We construct a magnetic soliton by double Wick rotating the static electrically charged black hole in three-dimensional Einstein--Gauss--Bonnet gravity. We match the boundary metri…
Unitary evolution of an evaporating black hole in canonical quantum gravity
Sijia Wang, Robert B. Mann, Dong-han Yeom
We propose a framework for understanding the information loss paradox in the context of canonical quantum gravity. We first revisit several approaches to black hole evaporation tha…
Acceleration in 3D Einstein-Gauss-Bonnet Gravity
Cendikiawan Suryaatmadja, Dong-han Yeom, Robert Mann
We present a new class of exact solutions in Einstein-Gauss-Bonnet gravity in 2+1 dimensions that generalize the C-metric. This set of metrics equals the C-metric multiplied by a f…
Gravitational equal-area law and critical phenomena of cuspy black hole shadow
Shao-Wen Wei, Chao-Hui Wang, Yu-Peng Zhang +2
The formation of a cusp on a black hole shadow is a striking signature of physics beyond the Kerr paradigm. Using the Konoplya-Zhidenko metric, a general parametrized deformation o…
Quantum coherent dynamics of quasiclassical spacetimes
Sijia Wang, Achintya Sajeendran, Dong-han Yeom +2
In a wide range of quantum gravity theories, quasiclassical geometries, which are solutions to the Einstein field equations approximately, are described by "coherent states." Here…
Isentropic process of Reissner-Nordström black holes: a possible excess of the entropy bound via a non-perturbative channel
Robert B. Mann, Dong-han Yeom
We study the implications of an isentropic processes applied to a Reissner-Nordström black hole. This process is possible if a black hole absorbs a particle with a specific ratio o…
Slowly rotating black hole solution to Einstein-Bel-Robinson gravity
Seyed Naseh Sajadi, Supakchai Ponglertsakul, Robert B. Mann
We study slowly rotating black hole solutions in the Einstein-Bel-Robinson gravity (EBR) in four dimensions. At the leading order in the rotation parameter, the only modification w…
Accelerated detector in a superposed spacetime
Lakshay Goel, Everett A. Patterson, María Rosa Preciado-Rivas +3
In pursuit of a full-fledged theory of quantum gravity, operational approaches offer insights into quantum-gravitational effects produced by quantum superposition of different spac…
Non-linearity and chaos in the kicked top
Amit Anand, Robert B. Mann, Shohini Ghose
Classical chaos arises from the inherent non-linearity of dynamical systems. However, quantum maps are linear; therefore, the definition of chaos is not straightforward. To address…
Signatures of Rotating Black Holes in Quantum Superposition
Cendikiawan Suryaatmadja, Cemile Senem Arabaci, Matthew P. G. Robbins +3
A new approach for operationally studying the effects of spacetime in quantum superpositions of semiclassical states has recently been proposed by some of the authors. This approac…
Unruh phenomena and thermalization for qudit detectors
Caroline Lima, Everett Patterson, Erickson Tjoa +1
We study Unruh phenomena for a qudit detector coupled to a quantized scalar field, comparing its response to that of a standard qubit-based Unruh-DeWitt detector. We show that ther…
Charged Randall-Sundrum black holes in Higher Dimensions
Michael Meiers, Luke Bovard, Robert Mann
We extend some solutions for black holes in the Randall-Sundrum theory with a single brane. We consider a generalised version of the extremal black hole on the brane in n + 1 dimen…
