This talk will be about an interacting particle system driven by two forces: a repulsive pairwise interaction between them, and a confining potential. At a positive temperature, their behavior is driven by the Gibbs measure associated with this Hamiltoninan. We will be interested in the rate of convergence to the mean-field limit as the number of particles tends to infinity. To this end, we will formulate and prove concentration inequalities. We will be interested in three cases: a Coulomb interaction, a Riesz-type interaction, and a general interaction.
