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_…
Domain Growth and Aging in a Phase Separating Binary Fluid Confined Inside a Nanopore
Saikat Basu, Suman Majumder, Raja Paul +1
Hydrodynamics is known to have strong effects on the kinetics of phase separation. There exist open questions on how such effects manifest in systems under confinement. Here, we ha…
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…
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…
