Existence of weak solutions to time-dependent mean-field games

Here, we establish the existence of weak solutions to a wide class of time-dependent monotone mean-field games (MFGs). Expand abstract.

Derivation of the Landau-Pekar equations in a many-body mean-field limit

We consider the Fr\"ohlich Hamiltonian in a mean-field limit where many bosonic particles weakly couple to the quantized phonon field. Expand abstract.

Equivalence of ensembles in Curie-Weiss models using coupling techniques

We consider equivalence of ensembles for two mean field models: the discrete, standard Curie-Weiss model and its continuum version, also called the mean-field spherical model. Expand abstract.

Mean-field density of states of a small-world model and a jammed soft spheres model

We consider a class of random block matrix models in $d$ dimensions, $d \ge 1$, motivated by the study of the vibrational density of states (DOS) of soft spheres near the isostatic point. Expand abstract.

The mean-field limit of quantum Bose gases at positive temperature

We prove that the grand canonical Gibbs state of an interacting quantum Bose gas converges to the Gibbs measure of a nonlinear Schr\"odinger equation in the mean-field limit, where the density of the gas becomes large and the interaction strength is proportional to the inverse density.

Rigorous results on topological superconductivity with particle number conservation

These results show that many of the remarkable properties of mean-field models of topological superconductivity persist in more realistic models with number-conserving dynamics. Expand abstract.

Mean field games with branching

For this reason, we introduce a branching mechanism in the population of agents and obtain a variation on the mean field game problem. Expand abstract.

Some aspects of the Markovian SIRS epidemics on networks and its mean-field approximation

Then, we pass to consider a first-order mean-field approximation of the exact model. Expand abstract.
