Domain growth in lipid membranes and the budding instability
Jean Wolff, Fabrice Thalmann, Carlos Marques +3
We investigate the growth of a circular domain in a phase-separating lipid membrane and its relation to the budding instability. We describe the in-plane dynamics with a conserved,…
Non-ideal mixing of lipids: a molecular dynamics perspective
L. Berezovska, R. Kociurzynski, F. Thalmann
Lipid membranes have complex compositions and modeling the thermodynamic properties of multi-component lipid systems remains a remote goal. In this work we attempt to describe the…
Rotational and translational drags of a Janus particle close to a wall and a lipid membrane
Vaibhav Sharma, Florent Fessler, Fabrice Thalmann +2
Hypothesis: Measuring rotational and translational Brownian motion of single spherical particles reveals dissipations due to the interaction between the particle and the environmen…
Internal lipid bilayer friction coefficient from equilibrium canonical simulations
Othmene Benazieb, Lisa Berezovska, Fabrice Thalmann
A fundamental result in the theory of Brownian motion is the Einstein-Sutherland relation between mobility and diffusion constant. Any classical linear response transport coefficie…
Excimer formation of pyrene labeled lipids interpreted by means of coarse-grained molecular dynamics simulations
Pierre Ayoub, Fabrice Thalmann
The excimer formation dynamics of pyrene-labeled molecules in lipid bilayers depends on molecular motion over distances of the order of 1-2 nm. From the concentration dependence of…
Perturbing the catenoid: stability and mechanical properties of non-axisymmetric minimal surfaces
Friedrich Walzel, Alice Requier, Kevin Boschi +6
Minimal surface problems arise naturally in many soft matter systems whose free energies are dominated by surface or interface energies. Of particular interest are the shapes, stab…
Stress overshoot, hysteresis and Bauschinger effect in sheared dense colloidal suspensions
Dmytro Kushnir, Céline Ruscher, Eckhard Bartsch +2
The mechanical non-linear response of dense Brownian suspensions of polymer gel particles is studied experimentally and by means of numerical simulations. It is shown that the resp…
Ripple-like instability in the simulated gel phase of finite size phosphocholine bilayers
Vivien Walter, Céline Ruscher, Adrien Gola +3
Atomistic molecular dynamics simulations have reached a degree of maturity that makes it possible to investigate the lipid polymorphism of model bilayers over a wide range of tempe…
A fluid bilayer phase in aqueous mixtures of fatty alcohol and cationic surfactant
Tiago Espinosa de Oliveira, Fabien Leonforte, Luc Nicolas-Morgantini +4
The phase of lipid bilayers is a fluid self-assembled state, key to the formulation of cosmetics, detergents and pharmaceutics. Despite having been extensively scrutinized in…
A machine learning assessment of the two states model for lipid bilayer phase transitions
Viven Walter, Céline Ruscher, Olivier Benzerara +2
We have adapted a set of classification algorithms, also known as Machine Learning, to the identification of fluid and gel domains close to the main transition of dipalmitoyl-phosp…
Thermodynamic Approach to Phase Coexistence in Ternary Phospholipi-Cholesterol Mixtures
Jean Wolff, Carlos M. Marques, Fabrice Thalmann
We introduce a simple and predictive model for determining the phase stability of ternary phospholipid-cholesterol mixtures. Assuming that competition between the liquid and gel or…
Enhanced shear separation for chiral magnetic colloidal aggregates
C. I. Mendoza, C. M. Marques, F. Thalmann
We study the designing principles of the simplest colloidal propeller, an architecture built from four identical spheres that can couple translation with rotation to produce contro…
A schematic model for molecular affinity and binding with Ising variables
Fabrice Thalmann
After discussing the relevance of statistical physics in molecular recognition processes, we present a schematic model for ligand-receptor association based on an Ising chain. We d…
Collision induced spatial organization of microtubules
Vladimir A. Baulin, Carlos M. Marques, Fabrice Thalmann
The dynamic behavior of microtubules in solution can be strongly modified by interactions with walls or other structures. We examine here a microtubule growth model where the incre…
What is in a pebble shape?
D. J. Durian, H. Bideaud, P. Duringer +3
We propose to characterize the shapes of flat pebbles in terms of the statistical distribution of curvatures measured along the pebble contour. This is demonstrated for the erosion…
