Directed polymer in correlated environment
Francesca Cottini (Sorbonne Université)
Directed polymers in random environments describe a perturbation of the simple random walk given by a random disorder (environment). The partition functions of this model [...]

Invasion Dynamics of a Birth–Death Process in a Quasi-Critical Regime: Applications to Cancer.
Nadia BELMABROUK (École Polytechnique)
During the emergence of cancer, a mutant cell can develop its own subpopulation and progressively invade the resident population. We start from a single mutant [...]

Mean-field analysis of the training dynamics of two-layer neural networks
Arnaud Descours (ISFA, Lyon)
Training neural networks via stochastic gradient descent (SGD) amounts to solving a complex, non-convex optimization problem. Inspired by statistical mechanics, the mean-field approach provides a [...]

The partition function of β-ensembles with complex potentials
Alex Little (ENS Lyon)
The asymptotic behaviour of the partition function is one of the central questions of statistical mechanics. In our work we consider this problem when the [...]

Large-scale concentration and relaxation for mean-field Langevin particle systems
Songbo WANG (Univsersité de Nice)
We study the Langevin dynamics of diffusive particles with regular pairwise interactions under mean-field scaling. By approximating empirical distributions with conditional distributions, we establish coercive [...]
