Non-relativistic CFTs and gravity
📍 London
Mukund Rangamani
(Durham)
Abstract:
I will discuss how field theories with non-relativistic conformal symmetry, arise naturally in string theory and furthermore describe how one can construct gravitational duals for such theories. Using the gravitational description we will discuss aspects of thermal physics of these theories.

String creation and effective field theory.
Janet Hung
(DAMTP, Cambridge)
Abstract:
We will discuss the missing pieces in the understanding of the
effective field theory description of string creation, the S-dual of the
Hanany-Witten effect, both in the open and closed string picture. We
explain the origin of a crucial bare Chern-Simons term, that used to be
added in by hand for consistency. Finally we summarize the remaining
unsettled issues, concerning the need to modify the DBI action and the
interpretation of the bare term in M-theory.
