Mysteries in the Conformal Bootstrap
Discussion group led by David Poland
1:30pm|Bloomberg Hall Physics Library

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 as an Effective Field Theory - Recent Progress and Open Problems
Discussion Group led by Loganayagam Ramalingam
1:30pm|Bloomberg Hall Physics Library

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...

Kitaev's Model and AdS_2
Discussion Group led by Douglas Stanford
1:30pm|Bloomberg Hall Physics Library

(Building on work by Sachdev, Ye, Parcollet and Georges) Kitaev has proposed a simple quantum mechanical model as a dual to an AdS_2 black hole. It would be nice to understand the bulk theory. (Is it local? Is there randomness? How is conformal...

Euclidean Wormholes
Discussion Group led by Juan Maldacena
11:00am|Bloomberg Hall Physics Library

Euclidean wormholes are simple solutions such as the one discussed in
the attached paper by Giddings and Strominger. (see email)
You can also have a look at the attached paper by Coleman.
You can also look at http://arxiv.org/abs/0705.2768 and find...

Reciprocity Laws
1:30pm|Bloomberg Hall Physics Library

I will introduce polynomial congruences and indicate why number theorists might care about them. I will then describe reciprocity laws which predict the number of solutions to a polynomial congruence in terms of discrete subgroups of Lie groups. The...
