Probability Seminar: Geometry of half-space log-gamma polymers

Seminar | December 14 | 3:10-4 p.m. | 340 Evans Hall

Speaker/Performer:  Sayan Das, Columbia University

Sponsor:  Department of Statistics

Directed polymers in a random environment is a classical model to study how random impurities affect a polymer chain. The half-space variant of directed polymers studies how polymer chains behave in presence of a wall. In this talk, I will focus on the half-space log-gamma polymer model which is integrable. I will discuss some of the recent results regarding transversal fluctuations of the free energy of this model in both unbound and bound phases. This is based on two ongoing works: one with Guillaume Barraquand and Ivan Corwin, and one with Weitao Zhu.
