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_…

Density-field structures in a few systems undergoing velocity ordering
Subir K. Das, Sohini Chatterjee, Wasim Akram +3
We consider two (off-lattice) varieties of out-of-equilibrium systems, viz., granular and active matter systems, that, in addition to displaying velocity ordering, exhibit fascinat…

Quicker flocking in aligning active matters for noisier beginning
Sohini Chatterjee, Sohom Das, Purnendu Pathak +2
The constituents in a class of active matter systems change their directions of motion by being influenced by the velocities of the neighbors. Such systems may undergo phase transi…
