Ordinary materials are "passive" in the sense that their constituents are typically made by inert particles which
are subjected to thermal fluctuations, internal interactions and external fields but do not move on their own. Living systems, like schools of fish, swarms of birds, pedestrians and swimming microbes are called "active matter" since they are composed of self-propelled constituents. Active matter is intrinsically in nonequilibrium and exhibits a plethora of novel phenomena as revealed by a recent combined effort of statistical theory, computer simulation and real-space experiments. This talk focusses on the statistical physics of artificial colloidal microswimmers as key examples of active soft matter.

[1]. A number of single-particle and collective phenomena in active colloids will be addressed ranging from
circle swimming to the formation of active colloidal molecules.
