Dynamical reweighting for estimation of fluctuation formulas
Raphaël Gastaldello, Gabriel Stoltz, Urbain Vaes
We propose a variance reduction method for calculating transport coefficients in molecular dynamics using an importance sampling method via Girsanov's theorem applied to Green--Kub…

Mean-field limits for interacting diffusions with colored noise: phase transitions and spectral numerical methods
S. N. Gomes, G. A. Pavliotis, U. Vaes
In this paper we consider systems of weakly interacting particles driven by colored noise in a bistable potential, and we study the effect of the correlation time of the noise on t…

A linear, second-order, energy stable, fully adaptive finite-element method for phase-field modeling of wetting phenomena
B. Aymard, U. Vaes, M. Pradas +1
We propose a new numerical method to solve the Cahn-Hilliard equation coupled with non-linear wetting boundary conditions. We show that the method is mass-conservative and that the…
