Modeling active colloids: From active brownian particles to hydrodynamic and chemical fields

A Zöttl, H Stark - Annual Review of Condensed Matter Physics, 2023 - annualreviews.org
Active colloids are self-propelled particles moving in viscous fluids by consuming fuel from
their surroundings. Here, we review the numerical and theoretical modeling of active …

Active Ornstein–Uhlenbeck model for self-propelled particles with inertia

GHP Nguyen, R Wittmann… - Journal of Physics …, 2021 - iopscience.iop.org
Self-propelled particles, which convert energy into mechanical motion, exhibit inertia if they
have a macroscopic size or move inside a gaseous medium, in contrast to micron-sized …
