Enhanced adiabatic index for hot neutron-rich matter from microscopic nuclear forces

We investigate the adiabatic index $\Gamma_{\mathrm{th}}$ of hot and dense nuclear matter from chiral effective field theory and find that the results are systematically larger than from typical mean field models. Expand abstract.

Combined Mean Field Limit and Non-relativistic Limit of Vlasov-Maxwell Particle System to Vlasov-Poisson System

In this paper we consider the mean field limit and non-relativistic limit of relativistic Vlasov-Maxwell particle system to Vlasov-Poisson equation. Expand abstract.

Uniform Poincar{'e} and logarithmic Sobolev inequalities for mean field particles systems

Our uniform log-Sobolev inequality, based on Zegarlinski's theorem for Gibbs measures, allows us to obtain the exponential convergence in entropy of the McKean-Vlasov equation with an explicit rate constant, generalizing the result of [10] by means of the displacement convexity approach, or [19, 20] by Bakry-Emery technique or the recent...

Fluctuations for Spatially Extended Hawkes Processes

In the present paper, we complement this result by studying the fluctuations of such a stochastic system around its mean field limit u(t,x). Expand abstract.

The Dynamics of Multi-agent Multi-option Decision Making

Introducing the agent level back into collective decision-making models uncovers a plethora of novel collective behaviors beyond agreement and mean-field descriptions of disagreement and polarization. Expand abstract.

Quantum fluctuations inhibit symmetry breaking in the HMF model

It is widely believed that mean-field theory is exact for a wide-range of classical long-range interacting systems. Expand abstract.

Critical exponents and fine-grid vortex model of the dynamic vortex Mott transition in superconducting arrays

We study the dynamic vortex Mott transition in two-dimensional superconducting arrays in a magnetic field with $f$ flux quantum per plaquette. Expand abstract.

Extended Mean Field Games with Singular Controls

We prove the existence of equilibria by first considering the corresponding mean field games with continuous controls instead of singular controls and then taking approximation. Expand abstract.

Dynamical correlations and pairwise theory for the symbiotic contact process on networks

In particular, the stationary state of the 2SCP model on random regular networks is very accurately reproduced by the pairwise mean-field, even for relatively small values of vertex degree, where expressive deviations of the standard mean-field are observed. Expand abstract.
