Collective dynamics of chemically active particles trapped at a fluid interface
Alvaro Domínguez, P. Malgaretti, M. N. Popescu +1
Chemically active colloids generate changes in the chemical composition of their surrounding solution and thereby induce flows in the ambient fluid which affect their dynamical evo…
Structure and dynamics of binary liquid mixtures near their continuous demixing transitions
Sutapa Roy, S. Dietrich, Felix Höfling
The dynamic and static critical behavior of five binary Lennard-Jones liquid mixtures, close to their continuous demixing points (belonging to the so-called model H' dynamic univer…
Critical Casimir interactions between Janus particles
M. Labbé-Laurent, S. Dietrich
Recently there is strong experimental and theoretical interest in studying the self-assembly and the phase behavior of patchy and of Janus particles, which form colloidal suspensio…
Critical Casimir forces between defects in the 2D Ising model
Piotr Nowakowski, Anna Maciołek, Siegfried Dietrich
An exact statistical mechanical derivation is given of the critical Casimir interactions between two defects in a planar lattice-gas Ising model. Each defect is a group of nearest-…
Wetting hysteresis induced by nanodefects
Alberto Giacomello, Lothar Schimmele, Siegfried Dietrich
Wetting of actual surfaces involves diverse hysteretic phenomena stemming from ever-present imperfections. Here we clarify the origin of wetting hysteresis for a liquid front advan…
