Seminar on Stochastic Processes

Title Confined planar Coulomb gases
Speaker, Affiliation Prof. Dr. Fredrik Viklund, KTH Royal Institute of Technology
Date, Time 23 September 2026, 17:15-18:45
Location HG G 43
Abstract I will discuss probabilistic and analytic aspects of two-dimensional Coulomb gases confined to Jordan domains, curves, and arcs. In particular, I will describe the asymptotic behavior of particle distributions as the number of particles tends to infinity. I will also explain how the Loewner energy and related quantities arise in the asymptotic expansion of the free energy. A key analytical tool throughout is the Grunsky operator. The talk is based on joint work with Kurt Johansson and Klara Courteaut.

Title From Dimers to Maximal Surfaces in Minkowski Space R^{2,1}
Speaker, Affiliation Prof. Dr. Marianna Russkikh, University of Notre Dame
Date, Time 14 October 2026, 17:15-18:45
Location HG G 43
Abstract We discuss a class of graph embeddings into Minkowski space R^{2,2} = C^{1,1}, called t-surfaces, which arise in the study of the planar dimer model. A t-surface consists of a (perfect) t-embedding together with its associated origami map. Perfect t-embeddings were recently introduced as a key tool for proving that the gradient of the dimer height function converges to that of the Gaussian Free Field in a canonically associated metric, under suitable technical assumptions. After introducing the notion of a t-embedding, we describe a construction of perfect t-embeddings for regular hexagons of the hexagonal lattice. For which the corresponding t-surfaces converge to space-like maximal surfaces in Minkowski space R^{2,1}. As a consequence, this construction yields a new proof of the convergence of fluctuations of the dimer height function to the Gaussian Free Field in the conformal structure induced by the limiting maximal surface.
