Abstract: The Miura transformation is a powerful formalism to construct generators of vertex operator algebras in free field representation. In this talk, I will explain that Miura operators are R-matrices of a certain quantum algebra, and comment...

Abstract: Holographic tensor networks model AdS/CFT, but so far they have been limited by involving only systems that are very different from gravity. Unfortunately, we cannot straightforwardly discretize gravity to incorporate it, because that...

Abstract: I will describe a double scaled matrix and tensor integral whose Feynman diagrams can be organized in a 3d topological expansion which agrees term by term with partition functions of 3d gravity. The integral is taken over CFT2 data, and...

Abstract: The TTbar deformation is a holographic theory describing holography a finite distance in the bulk.   If this theory can be UV completed, it could be a model of nonperturbative bulk quantum gravity.  However, it seems to be a non-unitary...

Abstract: I will give a lightning review of results on this subject from 1988-1998 and then describe more recent developments, mostly current work in progress.  First, I will describe topological twisting of Lagrangian N=2 d=4 field theories in...

Abstract: Post-inflationary QCD axion is an attractive solution to the Strong CP problem because of the possibility to uniquely predict the axion mass if axion makes up all of dark matter. On the other hand, QCD axion models often suffer from the so...

Abstract: I will talk about the invariants of topologically ordered states of quantum lattice systems that generalize Berry classes and can be defined for any gapped state in any dimension. The equivariant version of such invariants unifies and...

Abstract: The moduli space of curves, M_g, is an object of pivotal interest in mathematics and theoretical physics. Even though it has been studied with tremendous effort, little is known about its topology. For instance, the total dimension of the...

Abstract: I will showcase the computation of the next-to-leading order scattering waveform in classical gravity using...

Abstract: The entropy of supersymmetric black holes in string theory compactifications can be related to that of a D- or...
