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…
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…
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…
On the Stress Tensor for Asymptotically Flat Gravity
Robert B. Mann, Donald Marolf, Robert McNees +1
The recent introduction of a boundary stress tensor for asymptotically flat spacetimes enabled a new construction of energy, momentum, and Lorentz charges. These charges are known…
States of Negative Energy and
Keith Copsey, Robert B. Mann
We develop a careful definition of energy for nonsupersymmetric warped product asymptotically solutions which include a nonzero p-form. In the case of an electri…
Charged Fermions Tunnelling from Kerr-Newman Black Holes
Ryan Kerner, R. B. Mann
We consider the tunnelling of charged spin-(1/2) fermions from a Kerr-Newman black hole and demonstrate that the expected Hawking temperature is recovered. We discuss certain techn…
