SUMMARY:Séminaire du LPTMS: Jean Wolff - LPTMS\, salle 201\, 2ème étage\
 , Bât 100\, Campus d'Orsay - 2 Juin 15 11:00
DESCRIPTION:Budding of domains in mixed bilayer membranes\nJ. Wolff\,  Ins
 titut Charles Sadron (UPR CNRS)\, Strasbourg\nWe propose a model that acco
 unts for budding behavior of domains in lipid bilayers\, where each of the
  bilayer leaflets has a coupling between its local curvature and local lip
 id composition. The compositional asymmetry between the two monolayers lea
 ds to an overall spontaneous curvature. The membrane free energy contains 
 three contributions: bending energy\, line tension\, and a Landau free ene
 rgy for a lateral phase separation. Within a mean-field treatment\, we obt
 ain various phase diagrams which contain fully-budded\, dimpled and flat s
 tates.\nIn particular\, for some range of membrane parameters\, the phase 
 diagrams exhibit a tri-critical behavior as well as three-phase coexistenc
 e region. The global phase diagrams can be divided into three types and ar
 e analyzed in terms of the curvature-composition coupling parameter and do
 main size.\n\n&nbsp\;\n\n\n\nRef.: J.Wolff\, S. Komura\, D. Andelman\, PRE
