Dynamics of a collection of active particles on a two-dimensional periodic undulated surface
Vivek Semwal, Shambhavi Dikshit, Shradha Mishra
We study the dynamics of circular active particles (AP) on a two dimensional periodic undulated surface. Each particle has an internal energy mechanism which is modeled by an activ…
Polar flock with bond disorder
Jay Prakash Singh, Sudipta Pattanayak, Shradha Mishra
In this study, we introduce a minimal model for a collection of polar self-propelled particles (SPPs) on a two-dimensional substrate where each particle has a different ability to…
Active nematics with quenched disorder
Sameer Kumar, Shradha Mishra
We introduce a two-dimensional active nematic with quenched disorder. We write the coarse-grained hydrodynamic equations of motion for slow variables, viz. density, and orientation…
Dynamics of a particle moving in a two dimensional Lorentz lattice gas
Pranay Bimal Sampat, Sameer Kumar, Shradha Mishra
We study the dynamics of a particle moving in a square two-dimensional Lorentz lattice-gas. The underlying lattice-gas is occupied by two kinds of rotators, "right-rotator (R)" and…
Speed inhomogeneity accelerates the information transfer in polar flock
Sudipta Pattanayak, Jay Prakash Singh, Manoranjan Kumar +1
A collection of self-propelled particles (SPPs) shows coherent motion and exhibits a true long range ordered (LRO) state in two dimensions. Various studies show that the presence o…
