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…
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…
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…
Diffusion of Colloidal Rods in Corrugated Channels
Xiang Yang, Qian Zhu, Chang Liu +5
In many natural and artificial devices diffusive transport takes place in confined geometries with corrugated boundaries. Such boundaries cause both entropic and hydrodynamic effec…
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…
