Aggressive Phase Separation in Dense Mixtures of Passive and Active Particles
Purnendu Pathak, Gokul Upadhyay, Subir K. Das
Using Vicsek-like self-propulsion rule, we study kinetics of liquid-liquid phase separation in mixtures of passive and active particles. For evolutions following temperature quench…
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…
Multiscale Phase Separation in Chemophoretic Active Matter
Manisha Jhajhria, Subir K. Das, Snigdha Thakur
Nonreciprocal interactions in active matter provide interesting structure and dynamics. Here we investigate chemophoretic systems in which nonreciprocity arises from the asymmetric…
Phase Ordering in a few O(n) Symmetric Models: Slow Growth, Mpemba Effect and Experimental Relevance
Wasim Akram, Nalina Vadakkayil, Sohini Chatterjee +1
We study phase ordering dynamics in the three-dimensional nonconserved XY model, via Monte Carlo simulations, for quenches from paramagnetic phase to certain final temperatures $T_…
