abstract = {We study the phase behavior of ternary amphiphilic systems
in the framework of a curvature model with nonvanishing
spontaneous curvature. The amphiphilic monolayers can
arrange in different ways to form micellar, hexagonal,
lamellar, and various bicontinuous cubic phases. For the
latter case we consider both single structures (one
monolayer) and double structures (two monolayers). Their
interfaces are modeled by the triply periodic surfaces of
constant mean curvature of the families G, D, P, C(P), I-WP,
and F-RD. The stability of the different bicontinuous cubic
phases can be explained by the way in which their universal
geometrical properties conspire with the concentration
constraints. For vanishing saddle-splay modulus <(kappa)over
bar>, almost every phase considered has some region of
stability in the Gibbs triangle. Although bicontinuous cubic
phases are suppressed by sufficiently negative values of the
saddle-splay modulus <(kappa)over bar>, we find that they
can exist for considerably lower values than obtained
previously. The most stable bicontinuous cubic phases with
decreasing <(kappa)over bar>< 0 are the single and double
gyroid structures since they combine favorable topological
properties with extreme volume fractions. (C) 2000 American
