Black Holes as Effective Geometries
Vijay Balasubramanian, Jan de Boer, Sheer El-Showk +1
Gravitational entropy arises in string theory via coarse graining over an underlying space of microstates. In this review we would like to address the question of how the classical…
Black Hole Berry Phase
Jan de Boer, Kyriakos Papadodimas, Erik Verlinde
Supersymmetric black holes are characterized by a large number of degenerate ground states. We argue that these black holes, like other quantum mechanical systems with such a degen…
Open G2 Strings
Jan de Boer, Paul de Medeiros, Sheer El-Showk +1
We consider an open string version of the topological twist previously proposed for sigma-models with G2 target spaces. We determine the cohomology of open strings states and relat…
