A mean field approach to model flows of agents with path preferences over a network

Then, a bi-level optimization problem is formulated for an external controller who aims to induce a specific mean field equilibrium. Expand abstract.

On the diffusive-mean field limit for weakly interacting diffusions exhibiting phase transitions

As a by-product of our main results, we also analyse the energetic consequences of the central limit theorem for fluctuations around the mean field limit and derive optimal rates of convergence in relative entropy of the Gibbs measure to the (unique) limit of the mean field energy below the critical temperature.

Role of the Mean-field in Bloch Oscillations of a Bose-Einstein Condensate in an Optical Lattice and Harmonic Trap

When the mean field becomes large, soliton and vortex structures appear in the condensate wavefunction. Expand abstract.

Mean Field approach to stochastic control with partial information

Indeed, Mean Field Control Theory leads to very complex equations, like the Master equation, which is a nonlinear infinite dimensional P. Expand abstract.

Superheavy nuclei in microscopic collective Hamiltonian approach: the impact of beyond mean field correlations on the ground state and fission properties

The impact of beyond mean field effects on the ground state and fission properties of superheavy nuclei has been investigated in a five-dimensional collective Hamiltonian based on covariant density functional theory. Expand abstract.

Low-Energy Effective Theory at a Quantum Critical Point of the Two-Dimensional Hubbard Model: Mean-Field Analysis

We complement previous functional renormalization group (fRG) studies of the two-dimensional Hubbard model by mean-field calculations. Expand abstract.

Convergence Analysis of Machine Learning Algorithms for the Numerical Solution of Mean Field Control and Games: II -- The Finite Horizon Case

Furthermore, although the first approach is designed for mean field control problems, the second is more general and can also be applied to the FBSDE arising in the theory of mean field games. Expand abstract.

Mean field approximation of a heterogeneous population of plants in competition

The simulation of the mean-field distribution, consisting in a semi-Lagrangian scheme with an interpolation step using Gaussian process regression, is illustrated for a heterogeneous population model representing plants in competition for light. Expand abstract.
