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…
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…
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…
Escape kinetics of self-propelled particles from a circular cavity
Tanwi Debnath, Pinaki Chaudhury, Taritra Mukherjee +2
We numerically investigate the mean exit time of an inertial active Brownian particle from a circular cavity with single or multiple exit windows. Our simulation results witness di…
Activated barrier crossing dynamics of a Janus particle carrying cargo
Tanwi Debnath, Pulak Kumar Ghosh
We numerically study the escape kinetics of a self-propelled Janus particle, carrying a cargo, from a meta-stable state. We assume that the cargo is attached to the Janus particle…
