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…
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…
Enhanced motility in a binary mixture of active nano/microswimmers
Debajyoti Debnath, Pulak K. Ghosh, Vyacheslav R. Misko +3
It is often desirable to enhance the motility of active nano- or microscale swimmers such as, e.g., self-propelled Janus particles as agents of chemical reactions or weak sperm cel…
Diffusion of Chiral Janus Particles in Convection Rolls
Yunyun Li, Lihua Li, Fabio Marchesoni +2
The diffusion of an artificial active particle in a two-dimensional periodic pattern of stationary convection cells is investigated by means of extensive numerical simulations. In…
Non-Gaussian Normal Diffusion in a Fluctuating Corrugated Channel
Yunyun Li, Fabio Marchesoni, Debajyoti Debnath +1
A Brownian particle floating in a narrow corrugated (sinusoidal) channel with fluctuating cross section exhibits non-Gaussian normal diffusion. Its displacements are distributed ac…
Nonlocality of relaxation rates in disordered landscapes
Yunyun Li, Debajyoti Debnath, Pulak K. Ghosh +1
We investigate both analytically and by numerical simulation the relaxation of an overdamped Brownian particle in a 1D multiwell potential. We show that the mean relaxation time fr…
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…
