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 …

Exciting recent developments suggest that phase transitions represent an important and
ubiquitous mechanism underlying intracellular organization. We describe key experimental …

Active colloids are microscopic particles, which self-propel through viscous fluids by
converting energy extracted from their environment into directed motion. We first explain …

Self-propelled particles include both self-phoretic synthetic colloids and various
microorganisms. By continually consuming energy, they bypass the laws of equilibrium …

Differently from passive Brownian particles, active particles, also known as self-propelled
Brownian particles or microswimmers and nanoswimmers, are capable of taking up energy …

It is known that purely repulsive self-propelled colloids can undergo bulk liquid-vapor phase
separation. In experiments and large-scale simulations, however, more complex steady …

One characteristic feature of soft matter systems is their strong response to external stimuli.
As a consequence they are comparatively easily driven out of their ground state and out of …

Electric and magnetic fields have enabled both technological applications and fundamental
discoveries in the areas of bottom-up material synthesis, dynamic phase transitions, and …

Active colloids constitute a novel class of materials composed of colloidal-scale particles
locally converting chemical energy into motility, mimicking micro-organisms. Evolving far …

Within a simple model of attractive active Brownian particles, we predict flocking behavior
and challenge the widespread idea that alignment interactions are necessary to observe this …
