Abstract

We calculate from first principles the equation of state of a simple type of membrane: a monolayer consisting of lipid chain molecules with short-range repulsive and long-range attractive forces. An approximate solution to the packing problem of the hydrocarbon chains is obtained by using a mathematical analogy with the quantum gas of hard disks. The long-range attractive forces are incorporated in a mean-field approximation. The results are in qualitative agreement with experiments.
