Particle-Wall Alignment Interaction and Active Brownian Diffusion Through Narrow Channels

Poulami Bag, Shubhadip Nayak, Pulak Kumar Ghosh

We numerically examine the impacts of particle-wall alignment interactions on active species diffusion through a structureless narrow two-dimensional channel. We consider particle-…

Directed autonomous motion of active Janus particles induced by wall-particle alignment interactions

Poulami Bag, Tanwi Debnath, Shubhadip Nayak +1

We propose a highly efficient mechanism to rectify the motion of active particles by exploiting particle-wall alignment interactions. Through numerical simulations of active partic…

Large-scale dynamics in visual quorum sensing chiral suspensions

Yuxin Zhou, Qingqing Yin, Shubhadip Nayak +4

Motility induced phase separation is an efficient aggregation mechanism of active matter, yet biological systems exhibit richer organization through communication among constituent…

Diffusion Transients in Motility-Induced Phase Separation

Shubhadip Nayak, Poulami Bag, Pulak K. Ghosh +4

We numerically investigate normal diffusion in a two-dimensional athermal suspension of active particles undergoing motility-induced phase separation. The particles are modeled as…

Driven transport of active particles through arrays of symmetric obstacles

Shubhadip Nayak, Sohom Das, Poulami Bag +2

We numerically examine the driven transport of an overdamped self-propelled particle through a two-dimensional array of circular obstacles. A detailed analysis of transport quantif…

Non-Gaussian Normal Diffusion in Low Dimensional Systems

Qingqing Yin, Yunyun Li, Fabio Marchesoni +2

Brownian particles suspended in disordered crowded environments often exhibit non-Gaussian normal diffusion (NGND), whereby their displacements grow with mean square proportional t…
