abstract = {Inverse bicontinuous cubic phases are ubiquitous in
lipid-water mixtures and consist of a lipid bilayer forming
a cubic minimal surface, thereby dividing space into two
cubic networks of water channels. For small hydrocarbon
chain lengths, the monolayers can be modeled as parallel
surfaces to a minimal midsurface. The bending energy of the
cubic phases is determined by the distribution of Gaussian
curvature over the minimal midsurfaces which we calculate
for seven different structures (G, D, P, I-WP, C(P), S, and
F-RD). We show that the free-energy densities of the
structures G, D, and P are considerably lower than those of
the other investigated structures due to their narrow
distribution of Gaussian curvature. The Bonnet
transformation between G, D, and P implies that these phases
coexist along a triple line, which also includes an excess
water phase. Our model includes thermal membrane
undulations. Our qualitative predictions remain unchanged
when higher order terms in the curvature energy are
included. Calculated phase diagrams agree well with the
experimental results for 2:1 lauric acid/dilauroyl
phosphatidylcholine and water.},
