Particles approximation for some 1D kinetic Fokker-Planck equations with singular forces

In this paper we consider a system of $N$ particles on the real line evolving according to Newton’s law, interacting through a singular (repulsive) force deriving from the potential $\frac{\mathrm{\mid }x{\mathrm{\mid }}^{1-\alpha }}{1-\alpha }$ with $\alpha \in (0,1/8)$ and Brownian force. Thanks to the entropy dissipation along the Liouville equation associated to this particles system and a control of the mechanic energy, we establish a quantitative estimate which enables to conclude to a convergence/consistency the particles system toward the limiting Vlasov-Fokker-Planck equation with singular force.
