The aim of this annual workshop is to bring together mathematicians and physicists working on disordered or random systems, and to discuss recent developments on themes of common interest. Each day is devoted to a specific topic. Note that the 45th edition of the "Journées de Physique Statistique" takes place on January 29th and 30th.


Tuesday 27 January: 2D statistical mechanics: continuum and discrete.
        Moderator: Piet Lammers (Paris)

In recent years, there has been remarkable progress in the study of two-dimensional statistical mechanics. Increasingly, deep connections are emerging between discrete models and their continuous counterparts, offering new perspectives and tools to tackle longstanding problems.
The purpose of this workshop is to bring together researchers working on these developments across both the discrete and continuous settings. By fostering dialogue between different communities and across career stages, the day aims to promote the exchange of ideas, strengthen connections, and highlight exciting directions for future research.

Speakers: Rob Van den Berg (*) (Amsterdam), Joseph Chen (Paris), Barbara Dembin (Strasbourg), Trishen Gunaratnam (Mumbai and Bengaluru), Léonie Papon (Wien), Eveliina Peltola (Aalto and Bonn), Rémi Rhodes (Marseille).

Wednesday 28 January: Non-equilibrium and disordered interfaces.
        Moderator: Léonie Canet (Grenoble)

Stochastic interfaces arise in many different contexts, from condensed matter to hydrodynamics or ecology. They exhibit remarkable features, such as non-equilibrium scaling, non-Gaussian fluctuations, pattern formation and intermittency. In the presence of disorder, other interesting phenomena arise, from depinning to crumpling, including creeping dynamics and avalanches. Some of these aspects are theoretically understood and characterised, while others remain very challenging. The aim of this meeting is to bring together experts from different areas to give an overview of the recent advances in this field, and to spark fruitful exchanges.

Speakers: Jérémie Bec (Nice), Rodolfo Cuerno (Leganes), Vivien Lecomte (Grenoble), Amos Maritan (Padova), Dominique Mouhanna (Paris), Alberto Rosso (Orsay), Stéphane Santucci (Lyon).



The conference is free and open to all.
