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…

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_…

Critical Fluctuations at Finite-Time Dynamical Phase Transition

Nalina Vadakkayil, Massimiliano Esposito, Jan Meibohm

We explore the critical properties of the recently discovered finite-time dynamical phase transition in the non-equilibrium relaxation of Ising magnets after a temperature quench.…

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…

Should a hotter paramagnet transform quicker to a ferromagnet? Monte Carlo simulation results for Ising model

Nalina Vadakkayil, Subir K. Das

For quicker formation of ice, before inserting inside a refrigerator, heating up of a body of water can be beneficial. We report first observation of a counterpart of this intrigui…
