Abstract

A microscopic model for the ripple phase in phospholipid bilayers is presented including translational degrees of freedom for single molecules and two types of chain excitations. Induced by low-energy chain excitations, opposing molecules form flexible units in an intermediate temperature range and can accommodate a head/tail lattice misfit by introducing a lateral shift between head and tail positions. The ripple phase involves two different head packing modi with misfits of different sign and allows the tail region to pack in the preferred hexagonal structure. Observable properties are calculated using Monte Carlo sampling.
