Accelerating Solitons

3:00 pm – 4:00 pm (CDT)MIST M108

Speaker: Andrew Royston (Pennsylvania State University)Host: Falk Hassler

We show that the leading semiclassical behavior of soliton form factors at arbitrary momentum transfer is controlled by solutions to a new wave-like integro-differential equation that describes solitons undergoing acceleration. We work in the context of two-dimensional linear sigma models for concreteness, but our methods are purely semiclassical and ge... read more  »

Linearized Supergeometry of 11D,N =1⁄8 Superspace

3:00 pm – 4:00 pm (CDT)MIST M108

Speaker: Anindya Sengupta (Texas A&M University)Host: Falk Hassler

In 1978, Cremmer, Julia, and Scherk wrote down a (component) theory of eleven-dimensional Supergravity. Soon, in 1980, Brink and Howe gave a superspace formulation of this theory. The component theory required that dynamical fields to be on-shell for the closure of 11D,N=1 Supersymmetry. The same on-shell requirement followed from the Bianchi identities... read more  »

Worldsheet Correlators in AdS3

3:00 pm – 4:00 pm (CDT)Streaming Live

Speaker: Lorenz Eberhardt (Institute for Advanced Study)Host: Falk Hassler

We revisit the computation of string correlation functions in AdS3 with pure NS-NS flux from a worldsheet point of view. These correlators contain all the perturbative information about the spacetime CFT and the existence of winding strings in AdS3 makes them very rich. We propose a solution to the problem of computing these correlators. The winding cor... read more  »
