Mean-field phase diagram and spin glass phase of the dipolar Kagome Ising antiferromagnet

Moreover, they allow us to interpret the dynamical slowing down observed in the work of Hamp & al. as a remnant of a spin glass transition taking place at the mean-field level (and expected to be avoided in 2 dimensions). Expand abstract.

Spectral gap in $\mathcal O(n)$-model and chain of oscillators using Schr\"odinger operators

We study the dependence of the spectral gap for the generator of the continuous-time Glauber dynamics for all $\mathcal O(n)$-models with mean-field interaction and magnetic field, below the critical temperature on the number $N$ of particles. Expand abstract.

Implications of the fermion vacuum term in the extended SU(3) Quark Meson model on compact stars properties

We study the impact of the fermion vacuum term in the SU(3) quark meson model on the equation of state and determine the vacuum parameters for various sigma meson masses. Expand abstract.

Critical properties of the Ising model in hyperbolic space

In contrast to recent field theory calculations, which predict a non-mean-field fixed point for the ferromagnetic-paramagnetic phase-transition of the Ising model on three-dimensional hyperbolic space, our computations reveal a mean-field behavior. 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.

Intrinsic Cluster-Shaped Density Waves in Cellular Dynamical Mean-Field Theory

We discuss the limitations of periodization regarding this phenomenon, and we present mean-field density-wave models that reproduce CDMFT results at low energy in the superconducting state. Expand abstract.

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.
