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…
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…
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…
Cargo Towing by Artificial Swimmers
Debajyoti Debnath, Pulak K. Ghosh, Yunyun Li +2
An active swimmer can tow a passive cargo by binding it to form a self-propelling dimer. The orientation of the cargo relative to the axis of the active dimer's head is determined…
Diffusion of Chiral Janus Particles in a Sinusoidal Channel
Xue Ao, Pulak Kumar Ghosh, Yunyun Li +3
We investigate the transport diffusivity of artificial microswimmers, a.k.a. Janus particles, moving in a sinusoidal channel in the absence of external biases. Their diffusion cons…
