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 …

In this minireview, recent progress in our understanding of the basic physical principles of
microswimmers which perform a motion characterized by chirality is summarized. We …

Active matter agents consume internal energy or extract energy from the environment for
locomotion and force generation. Already, rather generic models, such as ensembles of …

We generalize the Vicsek model to describe the collective behavior of polar circle swimmers
with local alignment interactions. While the phase transition leading to collective motion in …

Active matter comprises individually driven units that convert locally stored energy into
mechanical motion. Interactions between driven units lead to a variety of nonequilibrium …

We investigate collective phenomena with rotationally driven spinners of concave shape.
Each spinner experiences a constant internal torque in either a clockwise or …

Collections of interacting, self-propelled particles have been extensively studied as minimal
models of many living and synthetic systems from bird flocks to active colloids. However, the …

Spherical Janus particles are one of the most prominent examples for active Brownian
objects. Here, we study the diffusiophoretic motion of such microswimmers in experiment …

One of the intrinsic characteristics of far-from-equilibrium systems is the nonrelaxational
nature of the system dynamics, which leads to novel properties that cannot be understood …

One of the most intriguing phenomena in active matter has been the gas–liquid-like motility-
induced phase separation (MIPS) observed in repulsive active particles. However …
