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…
Binary Mixtures in Linear Convection Arrays
Pulak Kumar Ghosh, Yuxin Zhou, Yunyun Li +2
We numerically investigated the dynamics of a mixture of finite-size active and passive particles in a linear array of convection rolls. The interplay of advection and steric inter…
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…
