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

For a large class of nonequilibrium systems, thermodynamic notions like work, heat, and, in
particular, entropy production can be identified on the level of fluctuating dynamical …

Environmental contamination is a major global challenge, and the effects of contamination
are found in most habitats. In recent times, the pollution by microplastics has come to the …

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

Active particles that are self-propelled by converting energy into mechanical motion
represent an expanding research realm in physics and chemistry. For micrometer-sized …

We study a system of purely repulsive spherical self-propelled particles in the minimal setup
inducing motility-induced phase separation (MIPS). We show that, even if explicit alignment …

Condensation of objects into stable clusters occurs naturally in equilibrium and driven
systems,,,. It is commonly held that potential interactions, depletion forces, or sensing are the …

Biological organisms and artificial active particles self-organize into swarms and patterns.
Open questions concern the design of emergent phenomena by choosing appropriate forms …

A remarkable feature of active matter is the propensity to self-organize. One striking instance
of this ability to generate spatial structures is the cluster phase, where clusters broadly …

Minimal models of active Brownian colloids consisting of self-propelled spherical particles
with purely repulsive interactions have recently been identified as excellent quantitative …
