Monte Carlo simulations are used to study the rippled Pβ′ phase in biomembranes conceived as a lamellar stack of lipid bilayers, each represented by a two-dimensional hexagonal lattice, in aqueous environment. The appearance of this intermediate phase between the ordered Lβ′ phase and the...

The basic interactions underlying the bilayer membranes have been studied in the biologically relevant soft confinement regime of interlayer spacing of 5–30Å. Due to its unique molecular structure, a lipid membrane shows both liquid-like and liquid crystalline (elastic) characteristics....
