A Brownian dynamics study of liquid-liquid phase separation in multi-scale chromatin networks
Léa Beaulès, Judith Miné-Hattab, Pierre Illien +1
In living cells, proteins involved in specialized biochemical functions are often spatially organized within biomolecular condensates. Increasing evidence suggests that some of the…
Solvent-induced memory effects in a model electrolyte
Sleeba Varghese, Benjamin Rotenberg, Pierre Illien
The fluctuations of ions in polar solvents remain poorly understood theoretically due to the complex coupling between ionic motion and solvent polarization. Indeed, while all-atom…
Closures of moment expansion of anisotropic active Brownian particles
Timothée Gautry, Maxime Deforet, Pierre Illien
We study analytically the dynamics of anisotropic active Brownian particles (ABPs), and more precisely their intermediate scattering function (ISF). To this end, we develop a syste…
Non-Gaussian density fluctuations in the Dean-Kawasaki equation
Louison Le Bon, Antoine Carof, Pierre Illien
Computing analytically the -point density correlations in systems of interacting particles is a long-standing problem of statistical physics, with a broad range of applications,…
The Dean-Kawasaki equation and stochastic density functional theory
Pierre Illien
The Dean-Kawasaki (DK) equation, which is at the basis of stochastic density functional theory (SDFT), was proposed in the mid-nineties to describe the evolution of the density of…
Stochastic density functional theory for ions in a polar solvent
Pierre Illien, Antoine Carof, Benjamin Rotenberg
In recent years, the theoretical description of electrical noise and fluctuation-induced effects in electrolytes has gained a renewed interest, enabled by stochastic field theories…
