States of quantum matter without quasiparticles can be more precisely characterized by their rapid approach to local thermal equilibrium: this is argued to happen in a shortest possible time of order (Planck’s constant)/((Boltmann’s constant)x...

I will discuss how to relate the entropy of BPSblack holes in AdS to counting of states in gaugetheory, presenting examples where this can besuccessfully done as well as examples where thisdoes not seem to work.

The observed small neutrino masses are one of the greatest mysteries in current theoretical particle physics. Many possible origins have been proposed so far, such as the see-saw mechanism, radiative corrections, or large extra dimensions. While all...

Motivated by black hole physics, we study the relationship between quantum chaos, holographic complexity, and fined grained notions of randomness. First, we develop a diagnostic of quantum chaos by directly considering the time evolution of a simple...

When a M5 branes probes the singular locus of the D,E type ALE orbifold, the M5 brane exhibits fractionation, which corresponds to activating tensor branch moduli of the 6d N=(1,0) SCFT living on the M5. I explain how the fractionation patterns can...

The Weak Gravity Conjecture demands the existence of superextremal states in any weakly coupled gauge theory including gravity. Some of its variants can constrain significantly the allowed effective field theories of inflation/relaxation. The...
