Anomalous temperature dependence in phase transitions via ballistic coalescence
Nalina Vadakkayil, Sutapa Roy, Jiarul Midya +1
We study kinetics of phase transitions within a single component Lennard-Jones model. For low enough particle densities disconnected clusters form that can move ballistically in an…
Critical surface adsorption of confined binary liquids with locally conserved mass and composition
Sutapa Roy, Felix Höfling
Close to a solid surface, the properties of a fluid deviate significantly from their bulk values. In this context, we study the surface adsorption profiles of a symmetric binary li…
Transient coarsening and the motility of optically heated Janus colloids in a binary liquid mixture
Juan Ruben Gomez-Solano, Sutapa Roy, Takeaki Araki +2
A gold-capped Janus particle suspended in a near-critical binary liquid mixture can self-propel under illumination. We have immobilized such a particle in a narrow channel and stud…
Phase separation around heated colloid in bulk and under confinement
Sutapa Roy, Anna Maciolek
We study the non-equilibrium coarsening dynamics of a binary liquid solvent around a colloidal particle in a presence of a time-dependent temperature gradient that emerges after te…
Solvent coarsening around colloids driven by temperature gradients
Sutapa Roy, S. Dietrich, Anna Maciolek
Using mesoscopic numerical simulations and analytical theory we investigate the coarsening of the solvent structure around a colloidal particle emerging after a temperature quench…
