SUMMARY:Séminaire du LPTMS: Julien Cividini - LPTMS\, salle 201\, 2ème é
 tage\, Bât 100\, Campus d'Orsay - 19 Déc 17 11:00
DESCRIPTION:Driven tracer with absolute negative mobility\nJulien Cividini 
 (Weizmann Institute\, Israël)\nInstances of negative mobility\, where a s
 ystem responds to a perturbation in a way opposite to naive expectation\, 
 have been studied theoretically and experimentally in numerous nonequilibr
 ium systems. After reviewing part of the literature on the topic\, we will
  consider a simple one-dimensional lattice model of a driven tracer in bat
 h. We will show that  contrary to previous expectations\, Absolute Negati
 ve Mobility (ANM)\, whereby current is produced in a direction opposite to
  the drive\, occurs around an equilibrium state. We derive analytical pred
 ictions for the mobility in the linear response regime. The high density r
 egime will help us elucidate the mechanism leading to ANM. The lattice mod
 el can be seen as a toy model for hard Brownian discs in a narrow planar c
 hannel. Molecular dynamics studies show that the hard discs model exhibits
  Negative Differential Mobility (NDM)\, but no ANM.
