Nonquenched rotators ease flocking and memorise it
Rakesh Das, Manoranjan Kumar, Shradha Mishra
We introduce a minimal model for a two-dimensional polar flock with nonquenched rotators, and show that the rotators make the usual macroscopic long-range order of the flock more r…
Enhanced dynamics of active Brownian particles in periodic obstacle arrays and corrugated channels
Sudipta Pattanayak, Rakesh Das, Manoranjan Kumar +1
We study the motion of an active Brownian particle (ABP) using overdamped Langevin dynamics on a two-dimensional substrate with periodic array of obstacles and in a quasi-one-dimen…
Polar flock in the presence of random quenched rotators
Rakesh Das, Manoranjan Kumar, Shradha Mishra
We study a collection of polar self-propelled particles (SPPs) on a two-dimensional substrate in the presence of random quenched rotators. These rotators act like obstacles which r…
Order-disorder transition in active nematic: A lattice model study
Rakesh Das, Manoranjan Kumar, Shradha Mishra
We introduce a lattice model for active nematic composed of self-propelled apolar particles,study its different ordering states in the density-temperature parameter space, and comp…
