SUMMARY:Séminaire du LPTMS: Pierre Illien - LPTMS\, salle 201\, 2ème éta
 ge\, Bât 100\, Campus d'Orsay - 20 Sep 16 11:00
DESCRIPTION:Active transport in complex environments\nPierre Illien (R. Pei
 erls Centre for Theor. Phys.\, Oxford University\, UK)\nUnderstanding the 
 dynamics of an active or a biased particle in a host medium which hinders 
 its motion is an ubiquitous problem of nonequilibrium statistical physics 
 with important applications\, from transport in biological systems to acti
 ve microrheology. Going beyond the usual effective descriptions of the env
 ironment of the active tracer\, we propose a model which takes explicitly 
 into account the correlations between the dynamics of the tracer and the r
 esponse of the bath. Relying on paradigmatic models of statistical mechani
 cs\, we determine analytically exact and approximate solutions to this out
 -of-equilibrium problem. They reveal many striking effects\, such as super
 diffusion in the high-density limit\, velocity anomalies or negative diffe
 rential mobility.\n
