Abstract: The uniqueness of the Kerr-de Sitter family of  black hole spacetimes as stationary solutions to the Einstein vacuum equations is a crucial ingredient to understanding the final states of positive cosmological constant universes, such as...

Abstract: I will describe recent progress towards understanding the gravitational path integral in AdS_3 quantum gravity and its boundary interpretation. A central question is: which spacetime topologies should be included in the path integral, and...

This semester, we will be beginning a *very informal* get-together every Monday of people interested in/working on phenomenology and new theories beyond the standard model.  The idea is to discuss over lunch, perhaps meet up around 12.20, grab lunch...

Abstract: There is a longstanding dream of realizing large-N Yang-Mills theory in D = 3,4 as a theory of confining strings. So far, our knowledge of this putative string is restricted to low energies, where one can use an effective field theory...

Abstract: Neutron stars and black holes represent the inevitable endpoints of stellar evolution for high-mass stars. Despite the apparent fine-tuning of the physical conditions necessary to produce them, neutron stars are abundant in the Galaxy. On...
