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_…
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…
Coarsening in the Long-range Ising Model with Conserved Dynamics
Soumik Ghosh, Subir K. Das
While the kinetics of domain growth, even for conserved order-parameter dynamics, is widely studied for short-range inter-particle interactions, systems having long-range interacti…
Simulations of Mpemba Effect in WATER, Lennard-Jones and Ising Models: Metastability vs Critical Fluctuations
Soumik Ghosh, Purnendu Pathak, Sohini Chatterjee +1
Via molecular dynamics simulations we study ICE formation in the TIP4P/Ice model that is known to describe structure and dynamics in various phases of WATER accurately. For this pu…
Finite-size Scaling in Kinetics of Phase Separation in Certain Models of Aligning Active Particles
Tanay Paul, Nalina Vadakkayil, Subir K. Das
To study the kinetics of phase separation in active matter systems, we consider models that impose a Vicsek-type self-propulsion rule on otherwise passive particles interacting via…
Mpemba Effect and Superuniversality across Orders of Magnetic Phase Transition
Sohini Chatterjee, Soumik Ghosh, Nalina Vadakkayil +3
The quicker freezing of hotter water, than a colder sample, when quenched to a common lower temperature, is referred to as the Mpemba effect (ME). While this counter-intuitive fact…
