"Physics of self-propelled colloids and microswimmers"

Le 20 décembre 2018
À 10h30
Amphithéâtre Henri Benoît, ICS

Vous êtes cordialement invités à la conférence de Hartmut Loewen, Institut für Theoretische Physik II, Düsseldorf, Germany, organisée par l'Institut Charles Sadron

Resumé : 

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.
After an introduction into the physics of active matter focussing on biological and artificial microswimmers as key examples of active soft matter [1], a number of single-particle and collective phenomena in active matter will be adressed ranging from active colloidal clusters [2] to inertial delay effects of granular vibrobots [3].
