"Topological defect lines and RG flows in 2D"

Speaker: Xi Yin, Harvard University

When: February 6, 2018 (Tue), 02:00PM to 03:00PM (add to my calendar)
Location: PRB 595

This event is part of the HET Seminar Series.

Topological defect lines in 2D generalize both global symmetries and Verlinde lines, and provide models of fusion categories without braiding. I will discuss their roles in CFTs and in constraining RG flows, and use them to determine the infrared (fully extended) topological quantum field theory in some examples of massive flows.
