Dear all of the SMAQ group,

this is to announce that Daniel Ueltschi will give a Colloquium talk at GSSI on

Loop models and the universal distribution of the loop lengths

this Thursday, May 4th, 2023 at 14.00 in the GSSI Auditorium (please NOTICE the unusual time).

The talk will be also streamed online at the link below:

Passcode: MATHatGSSI

Abstract. I will review several models that consist of one-dimensional loops living in the three-dimensional space. These models describe bosonic systems, and classical or quantum spin systems. Their common feature is that the joint distribution of their loop lengths has universal behaviour: It is always a Poisson-Dirichlet distribution. Most of this theory is conjectural, but it is backed by numerical studies and some partial rigorous results. 

Best,

Serena
