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…
Autonomous Ratcheting by Stochastic Resetting
Pulak K. Ghosh, Shubhadip Nayak, Jianli Liu +2
We propose a generalization of the stochastic resetting mechanism for a Brownian particle diffusing in a one-dimensional periodic potential: randomly in time, the particle gets res…
Escape Kinetics of an Underdamped Colloidal Particle from a Cavity through Narrow Pores
Shubhadip Nayak, Tanwi Debnath, Shovan Das +2
It is often desirable to know the controlling mechanism of survival probability of nano - or microscale particles in small cavities such as, e.g., confined submicron particles in f…
Directed Autonomous Motion and Chiral Separation of Self-Propelled Janus Particles in Convection Roll Arrays
Poulami Bag, Shubhadip Nayak, Tanwi Debnath +1
Self-propelled Janus particles exhibit autonomous motion thanks to engines of their own. However, due to randomly changing direction of such motion they are of little use for emerg…
Structure and diffusion of active-passive binary mixtures in a single-file
Tanwi Debnath, Shubhadip Nayak, Poulami Bag +2
We numerically study structure and dynamics of single files composed of active particles, as well as, active-passive binary mixtures. Our simulation results show that when the pers…
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…
