Аннотация:A coarse-grained spin model is constructed and used to study global phase behavior of ensembles of fluid membranes. This model encompasses both bending rigidity renormalization and steric entropy arising from coarse-graining of short-scale membrane fluctuations. It thus enables us to obtain, in a unified way, phase diagrams containing both uniform and periodic phases in microemulsions and binary systems of nonionic surfactant bilayers in a single solvent.
