Chemically active droplets in crowded environments
Jacques Fries, Roxanne Berthin, Chengjie Luo +4
Biomolecular condensates are essential for cellular organization and result from phase separation in systems far from thermodynamic equilibrium. Among various models, chemically ac…
Control of encounter kinetics by chemically active droplets
Jacques Fries, Roxanne Berthin, Marie Jardat +2
Biomolecular condensates play a crucial role in the spatial organization of living matter. These membrane-less organelles, resulting from liquid-liquid phase separation, operate fa…
Active droplets controlled by enzymatic reactions
Jacques Fries, Javier Diaz, Marie Jardat +3
The formation of condensates is now considered as a major organization principle of eukaryotic cells. Several studies have recently shown that the properties of these condensates a…
Phase transitions in chromatin: mesoscopic and mean-field approaches
Reda Tiani, Marie Jardat, Vincent Dahirel
By means of a minimal physical model, we investigate the interplay of two phase transitions at play in chromatin organization: (1) liquid-liquid phase separation (LLPS) within the…
Microscopic and stochastic simulations of chemically active droplets
Roxanne Berthin, Jacques Fries, Marie Jardat +2
Biomolecular condensates play a central role in the spatial organization of living matter. Their formation is now well understood as a form of liquid-liquid phase separation that o…
Isotropic active colloids: explicit vs. implicit descriptions of propulsion mechanisms
Jeanne Decayeux, Jacques Fries, Vincent Dahirel +2
Modeling the couplings between active particles often neglects the possible many-body effects that control the propulsion mechanism. Accounting for such effects requires the explic…
Enhanced diffusion of tracer particles in nonreciprocal mixtures
Anthony Benois, Marie Jardat, Vincent Dahirel +4
We study the diffusivity of a tagged particle in a binary mixture of Brownian particles with non-reciprocal interactions. Numerical simulations reveal that, for a broad class of in…
On analytical theories for conductivity and self-diffusion in concentrated electrolytes
Olivier Bernard, Marie Jardat, Benjamin Rotenberg +1
Describing analytically the transport properties of electrolytes, such as their conductivity or the self-diffusion of the ions, has been a central challenge of chemical physics for…
Conditions for the propulsion of a colloid surrounded by a mesoscale phase separation
Jeanne Decayeux, Marie Jardat, Pierre Illien +1
We study a two-dimensional model of an active isotropic colloid whose propulsion is linked to the interactions between solute particles of the bath. The colloid catalyzes a chemica…
Diffusion of a tracer in a dense mixture of soft particles connected to different thermostats
Marie Jardat, Vincent Dahirel, Pierre Illien
We study the dynamics of a tracer in a dense mixture of particles connected to different thermostats. Starting from the overdamped Langevin equations that describe the evolution of…
Spontaneous propulsion of an isotropic colloid in a phase-separating environment
Jeanne Decayeux, Vincent Dahirel, Marie Jardat +1
The motion of active colloids is generally achieved through their anisotropy, as exemplified by Janus colloids. Recently, there was a growing interest in the propulsion of isotropi…
Coarse-grained Models of Aqueous Solutions of Polyelectrolytes: Significance of Explicit Charges
Pauline Bacle, Marie Jardat, Virginie Marry +3
The structure of polyelectrolytes is highly sensitive to small changes in the interactions between its monomers. In particular, interactions mediated by counterions play a signific…
Can we describe charged nanoparticles with electrolyte theories? Insight from mesoscopic simulation techniques
Vincent Dahirel, Olivier Bernard, Marie Jardat
Electrolyte theories enable to describe the structural and dynamical properties of simple electrolytes in solution, such as sodium chloride in water. Using these theories for aqueo…
Hydrodynamic interactions between solutes in multiparticle collision dynamics
Vincent Dahirel, Xudong Zhao, Baptiste Couet +2
Multiparticle collision dynamics (MPCD) enables to simulate fluid dynamics including both hydrodynamics and thermal fluctuations. Its main use concerns complex fluids, where the so…
Computation of the Hydrodynamic Radius of Charged Nanoparticles from Non-equilibrium Molecular Dynamics
Lisa B. Weiss, Vincent Dahirel, Virginie Marry +1
We have used non-equilibrium molecular dynamics to simulate the flow of water molecules around a charged nanoparticle described at the atomic scale. These non-equilibrium simulatio…

We present a method to derive implicit solvent models of electrolyte solutions from all-atom descriptions; providing analytical expressions of the thermodynamic and structural prop…
Non-specific DNA-protein interaction: Why proteins can diffuse along DNA
Vincent Dahirel, Fabien Paillusson, Marie Jardat +2
The structure of DNA Binding Proteins enables a strong interaction with their specific target site on DNA. However, recent single molecule experiment reported that proteins can dif…
