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…
