Who's afraid of a negative lapse?
Robert Beig, Piotr T. Chruściel, Wan Cong
We rederive the Arnowitt-Deser-Misner equations in a framework in which the zeros of the lapse are innocuous, whether with or without changes of sign. We further develop and analys…
Gluing variations
Piotr T. Chruściel, Wan Cong
We establish several results on gluing/embedding/extending geometric structures in vacuum spacetimes with a cosmological constant in any spacetime dimensions , with emphasi…
Characteristic Gluing with 1. Linearised Einstein equations on four-dimensional spacetimes
Piotr T. Chruściel, Wan Cong
We establish a gluing theorem for linearised vacuum gravitational fields in Bondi gauge on a class of characteristic surfaces in static vacuum four-dimensional backgrounds with cos…
Quantum Detection of Conicity
Wan Cong, Jiri Bicak, David Kubiznak +1
We investigate the sensitivity of an Unruh-DeWitt detector to the global features of a deficit angle that are otherwise classically inaccessible. Specifically, we consider a detect…
Quantum Detection of Inertial Frame Dragging
Wan Cong, Jiri Bicak, David Kubiznak +1
A relativistic theory of gravity like general relativity produces phenomena differing fundamentally from Newton's theory. An example, analogous to electromagnetic induction, is gra…
Effects of Horizons on Entanglement Harvesting
Wan Cong, Chen Qian, Michael R. R. Good +1
We study the effects of horizons on the entanglement harvested between two Unruh-DeWitt detectors via the use of moving mirrors with and without strict horizons. The entanglement r…
Quantum Distinction of Inertial Frames: Local vs. Global
Wan Cong, Jiri Bicak, David Kubiznak +1
We study the response function of Unruh-deWitt detectors placed in a flat spacetime inside a thin matter shell. We show that the response function distinguishes between the local a…
Thermodynamic Instabilities of Generalized Exotic BTZ Black Holes
Wan Cong, Robert B. Mann
We examine the conjecture that black holes violating the reverse isoperimetric inequality have negative specific heat at constant volume . We test this conjecture on the famil…
Finely Split Phase Transitions of Rotating and Accelerating Black Holes
Niloofar Abbasvandi, Wasif Ahmed, Wan Cong +2
We investigate the thermodynamic phase behaviour of rotating and slowly accelerating AdS black holes. While we find some similarities with the non-rotating charged counterparts, su…
Snapping swallowtails in accelerating black hole thermodynamics
Niloofar Abbasvandi, Wan Cong, David Kubiznak +1
The thermodynamic behaviour of a charged and accelerating AdS black hole is studied in the context of extended phase space with variable cosmological constant. When compared to the…
