I will describe the calculation of the superconformal index for a large class of 4d N=2 theories, which arise by compactification of the maximally supersymmetric 6d theory on a punctured Riemann surface. The results for theories of type A have...

I will review the recent progress in the study of three dimensional U(N)_k Chern-Simons theories coupled to a massless boson or fermion in the fundamental representation. In particular, in the planar limit, one can determine the conformal fixed...

We examine some of constraints and cosmic clues for the nature of the dark matter. We use these clues and constraints as motivation to examine in greater detail a previously little explored class of models, where the dark matter carries a conserved...

I will review recent progress in uncovering the dualities between 3-dimensional large N vector models coupled to Chern-Simons gauge fields and higher spin gravity theories in 4-dimensional AdS space.
