SUMMARY:Séminaire du LPTMS: Julien Tailleur - LPTMS\, salle 201\, 2ème é
 tage\, Bât 100\, Campus d'Orsay - 29 Nov 16 11:00
DESCRIPTION:The Physics of Active Matter\nJulien Tailleur (Laboratoire Mati
 ère et Systèmes Complexes\, Université Denis-Diderot)\nOver the past te
 n years\, there has been a growing interest among physicists for 'active m
 atter'\, a codename that encompasses systems in which energy is taken from
  the environment to generate self-propulsion at the single particle level.
  Active particles\, such as run-and-tumble bacteria\, self-diffusiophoreti
 c colloids or actin filaments in motility assays\, are strongly out-of-equ
 ilibrium and exhibit much richer behaviours that their passive counterpart
 .\n\nIn this talk I will review recent progresses regarding the physics of
  active particles. I will show how simple concepts like pressure\, the for
 ce density exerted by assemblies of particles on their container\, play a 
 new role for active systems because of the lack of equation of state. I wi
 ll also show how new collective phenomena emerge\, from the transition to 
 collective motion to the existence of cohesive matter without cohesive for
 ces\, that have no counterpart in thermal equilibrium.
