Montag, 02.02.2026: Volume preserving mean curvature flow of capillary hypersurfaces
Prof. Dr. Carlo Sinestrari (Università di Roma "Tor Vergata")
We study the evolution of a convex capillary hypersurface in a half-space with prescribed contact angle at the boundary. The speed is given by a general positive power of the mean curvature minus its average, so that the enclosed volume remains constant. We show that the solution remains convex under the evolution, exists for all times and converges smoothly to a spherical cap as time goes to infinity. This work is in collaboration with Liangjun Weng (SNS Pisa).

Donnerstag, 05.02.2026: Rapid thermalization of lattice CSS codes
Sebastian Stengele (TUM)
CSS codes, such as the Toric code, are a widely studied class of quantum error-correcting codes. Understanding the thermalization time of these systems is important not only for error correction but also for applications like Gibbs sampling. We show that CSS codes on a lattice thermalize rapidly in any dimension at sufficiently high temperatures. For a special subclass, this rapid thermalization even holds at all positive temperatures. The central idea underlying our approach is to exploit the structure of CSS codes to decompose a quantity into two simpler, (almost) classical components, allowing us to apply tools from classical statistical mechanics to analyze the thermalization. This is based on joint work with Ángela Capel, Li Gao, Angelo Lucia, David Pérez-García, Antonio Pérez-Hernández, Cambyse Rouzé, and Simone Warzel.
