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...
