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...

I will describe a proposal for computing the Schur limit of the superconformal index of four-dimensional N = 2 field theories, which counts local operators in the UV, from the spectrum of BPS particles on the Coulomb branch. This proposal can be...

The goal of this discussion will be to first provide a broader picture and then to discuss the most recent work. I will review the general features of Low energy expansion of stringy amplitudes (tree level and one-loop) and it's relation to number...

I will discuss the discrete Liouville theory and its connection with cluster algebras, Teichmuller theory and supersymmetric gauge theories.References:The version of discrete Liouville I discuss has been formulated by many papers by Faddeev, Volkov...

I will review a few recent papers on 4d, N=3 superconformal field theories. References: arXiv:1512.03524arXiv:1512.06434arXiv:1602.08638

Abstract: I'll review a few recent papers that discuss the subject in the title, focusing on results based on AdS/CFT.References:https://arxiv.org/abs/1603.09745http://arxiv.org/pdf/1510.07911.pdfhttps://arxiv.org/abs/1509.06374For background, see:h...

I will describe a method for determining the spins of framed BPS states supported on line defects in 4d N=2 theories of class S. Via the 2d-4d correspondence, this amounts to constructing quantum holonomies on a punctured Riemann surface. The main...
