      abstract     = {Twist grain boundaries in bicontinuous cubic surfactant
                      phases are studied by employing a Ginzburg-Landau model of
                      ternary amphiphilic systems. Calculations are performed on a
                      discrete real-space lattice with periodic boundary
                      conditions for the lamellar L(alpha), gyroid G, diamond D,
                      and the Schwarz P phases for various twist angles. An
                      isosurface analysis of the scalar order parameter reveals
                      the structure of the surfactant monolayer at the interfaces
                      between the oil-rich and water-rich regions. The curvature
                      distributions show that the grain boundaries are minimal
                      surfaces. The interfacial free energy per unit area is
                      determined as a function of the twist angle for the G, D, P,
                      and lamellar phases using two complementary approaches: the
                      Ginzburg-Landau free-energy functional and a geometrical
                      approach based on the curvature energy of a monolayer. For
                      the L(alpha), G, and D phases the interfacial free energy
                      per unit area is very small, has the same order of
                      magnitude, and exhibits a nonmonotonic dependence on the
                      twist angle. The P phase is found to be unstable with
                      respect to the nucleation of grain boundaries.},
