Archive of IAS Physics Group Meetings

In the Friday seminar last week, Jennifer Lin talked about our joint work to characterize gravitational effective theories whose UV completions are dual to CFT’s on the boundary. I will discuss our attempt at its converse: how to characterize CFT’s...

We will discuss the various algebraic structures that appear when studying supersymmetric operators in SCFTs in various dimensions and the connections between them.

For example, topics may include relatively standard constructions such as chiral...

I will review some properties of BPS particles in four-dimensional N=2 field theories. I will emphasize recent developments and unsolved problems including restrictions on the charges of BPS particles, ideas about their large charge degeneracies...

We will discuss various aspects of the manifold of conformal field theories. Most of the time will be devoted to a review of older background material. It will allow us to give a unified and more conceptual treatment of some recent results.

Hi...

I will describe some situations where mysterious features have appeared in numerical studies of the conformal bootstrap. It is tempting to speculate that they may correspond to new CFTs, but we do not yet have good guesses for a microscopic...

Fluid dynamics is a centuries old phenomenological framework at the centre of various fields of science and engineering. But, we have only recently began to appreciate its claim as a paradigmatic effective field theory of mixed states and its...
