SUMMARY:Séminaire du LPTMS: Sergio Ciliberto - LPTMS\, salle 201\, 2ème 
 étage\, Bât 100\, Campus d'Orsay - 12 Sep 17 11:00
DESCRIPTION:\n\n\nThe Maxwell demon and Landuer's principle: from gedanken 
 to real experiments\n\n\n\nSergio Ciliberto (Laboratoire de Physique\, ENS
  de Lyon)\n\n\n\n\nDuring this talk we will recall the connections between
  information and thermodynamics. We will then discuss a specific example o
 f the measure of the Landauer's bound. Rolf Landauer argued that the erasu
 re of information is a dissipative process . A minimal quantity of heat\, 
 proportional to the thermal energy\, is necessarily produced when a classi
 cal bit of information is deleted. A direct consequence of this logically 
 irreversible transformation is that the entropy of the environment increas
 es unavoidably by a finite amount. We experimentally show the existence of
  the Landauer bound in a generic model of a one-bit memory. Using a system
  of a single colloidal particle trapped in a modulated double-well potenti
 al\, we establish that the mean dissipated heat saturates at the Landauer 
 bound in the limit of long erasure cycles. This result demonstrates the in
 timate link between information theory and thermodynamics. For a memory er
 asure procedure\, which is a logically irreversible operation\, a detailed
  Jarzynski Equality is verified\, retrieving the Landauer limit independen
 tly of the work done on the system.\n\nReferences :\n\n	Experimental verif
