Chiral active matter
B Liebchen, D Levis - Europhysics Letters, 2022 - iopscience.iop.org
Chiral active matter comprises particles which can self-propel and self-rotate. Examples
range from sperm cells and bacteria near walls to autophoretic L-shaped colloids. In this …

The role of disorder in the motion of chiral active particles in the presence of obstacles
The presence of obstacles is intuitively expected to hinder the diffusive transport of active
particles. However, for chiral active particles, a low density of obstacles near a surface can …

Hyper-Ballistic Superdiffusion of Competing Microswimmers
Hyper-ballistic diffusion is shown to arise from a simple model of microswimmers moving
through a porous media while competing for resources. By using a mean-field model where …
