Microscopic membrane elasticity and interactions among membrane inclusions: Interplay between the shape, dilation, tilt and tilt-difference modes
J. -B. Fournier
A phenomenological Landau elasticity for the shape, dilation, and lipid-tilt of bilayer membranes is developed. The shape mode couples with the sum of the monolayers' tilt, while t…
Coupling between membrane tilt-difference and dilation: a new ``ripple'' instability and multiple crystalline inclusions phases
J. -B. Fournier
A continuum Landau theory for the micro-elasticity of membranes is discussed, which incorporates a coupling between the bilayer thickness variation and the difference in the two mo…
Bi-defects of Nematic Surfactant Bilayers
J. -B. Fournier, L. Peliti
We consider the effects of the coupling between the orientational order of the two monolayers in flat nematic bilayers. We show that the presence of a topological defect on one bil…
A mode-coupling theory for the pasty rheology of soft glassy materials
P. Hebraud, F. Lequeux
In this paper, we introduce a simple mode-coupling model for concentrated suspensions under flow . This model exhibits a jamming transition, and stress vs shear rate relations whic…
