On the Geometry of Null Space-times
Speaker(s): Rob Leigh
Abstract: It is known that there is a relationship between conformal Carroll transformations and BMS symmetry. In this talk I will explore the geometry of generic Carroll structures which may be thought of as the basic underlying geometric structure on null hypersurfaces. A Carroll structure can be thought of... read more

Unitary Networks from the Exact Renormalization of Wavefunctionals
Speaker(s): Rob Leigh
Abstract: The exact renormalization group (ERG) for O(N) vector models at large N on flat Euclidean space admits an interpretation as the bulk dynamics of a holographically dual higher spin gauge theory on AdS_{d+1}. The generating functional of correlation functions of single trace operators is reproduced by... read more

PIRSA:12060021  ( MP4 Medium Res , MP4 Low Res , MP3 , PDF ) Which Format?
A Survey of Holographic Condensed Matter and Fluids
Speaker(s): Rob Leigh
Abstract: TBA
Date: 04/06/2012 - 3:30 pm

PIRSA:12020126  ( MP4 Medium Res , MP4 Low Res , MP3 , PDF ) Which Format?
Vorticity and Holography
Speaker(s): Rob Leigh
Abstract: Three-dimensional fluids with nontrivial vorticity can be described holographically. It is well-known that the Kerr-AdS geometry gives rise to a 'cyclonic' flow. Lorentzian Taub--NUT--AdS_4 geometries give rise to a rotating fluid with vortex flow.

PIRSA:06010004  ( MP4 Medium Res , MP3 , PDF ) Which Format?
Solving pure Yang-Mills in 2+1 dimensions
Speaker(s): Rob Leigh
Abstract: I review our recent work on confinement in 2+1 Yang Mills theory using Karabali-Nair variables. I'll discuss our successful prediction of the glueball spectrum, including the manifestations of the QCD string.
