We present new results for Renyi entropy in CFT ground states. In particular, we describe advances in computation across non-spherical entangling surfaces and for generic Renyi index, applicable to arbitrary CFTs. These include the first rigorous...

I’ll describe how to define and compute Euclidean partition functions of 4d N=1 theories on spaces that look like a circle times a simple three manifold. These partition functions can be interpreted as supersymmetric indices: supertraces over the...

We review recent progress that sheds light on the origin of conformal symmetry for general multi-charged rotating black holes both in four and five dimensions. We show that the asymptotic boundary conditions of these general asymptotically flat...

Recently a new and rather unexpected connection between condensed matter physics and algebraic topology has been noted. Namely, it appears that phases of matter with an energy gap, no long-range entanglement, and fixed symmetry can be classified...
