The Role of Angular Momentum and Cosmic Censorship in the (2+1)-Dimensional Rotating Shell Collapse
Robert B. Mann, John J. Oh, Mu-In Park
We study the gravitational collapse problem of rotating shells in three-dimensional Einstein gravity with and without a cosmological constant. Taking the exterior and interior metr…
Thermodynamics and phases in quantum gravity
Viqar Husain, R. B. Mann
We give an approach for studying quantum gravity effects on black hole thermodynamics. This combines a quantum framework for gravitational collapse with quasi-local definitions of…
Rigid motion revisited: rigid quasilocal frames
Richard J. Epp, Robert B. Mann, Paul L. McGrath
We introduce the notion of a rigid quasilocal frame (RQF) as a geometrically natural way to define a "system" in general relativity. An RQF is defined as a two-parameter family of…
Charging Black Saturn?
Brenda Chng, Robert Mann, Eugen Radu +1
We construct new charged static solutions of the Einstein-Maxwell field equations in five dimensions via a solution generation technique utilizing the symmetries of the reduced Lag…
Gravitinos Tunneling from Black Holes
Alexandre Yale, Robert B. Mann
Black hole radiation of gravitinos is investigated as the classically forbidden tunneling of spin-3/2 fermions through an event horizon. We show that all four spin states of the gr…
Supergravity on an Atiyah-Hitchin Base
Sean Stotyn, Robert Mann
We construct solutions to five dimensional minimal supergravity using an Atiyah-Hitchin base space. In examining the structure of solutions we show that they generically contain a…
