Domain Growth in the Active Model B: Critical and Off-critical Composition
Sudipta Pattanayak, Shradha Mishra, Sanjay Puri
We study the ordering kinetics of an assembly of {\it active Brownian particles} (ABPs) on a two-dimensional substrate. We use a coarse-grained equation for the composition order p…
Ordering Kinetics in the Active Model B
Sudipta Pattanayak, Shradha Mishra, Sanjay Puri
We undertake a detailed numerical study of the {\it Active Model B} proposed by Wittkowski et al. [Nature Comm. {\bf 5}, 4351 (2014)]. We find that the introduction of activity has…
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…
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…
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…
Collection of polar self-propelled particles with a modified alignment interaction
Sudipta Pattanayak, Shradha Mishra
We study the disorder-to-order transition in a collection of polar self-propelled particles interacting through a distance dependent alignment interaction. Strength of the interact…
