Title: Triply periodic surfaces and multiply continuous structures from the Landau model of microemulsions
Abstract: We present a method for the generation of periodic embedded surfaces of Gaussian curvature and multiply continuous phases. The are related to the local minima of the scalar order parameter Hamiltonian for microemulsions. In the bicontinuous the single surface separates the volume into two disjoint In some of our phases (multiply continuous) there is more one periodic surface that disconnects the volume into three or more subvolumes. We show that some of these surfaces are triply minimal surfaces. We have generated known minimal surfaces Schwarz primitive P, diamond D, and Schoen-Luzatti gyroid G and surfaces of high genus. We speculate that the structure of can be related to the high-genus gyroid structures, since high-genus surfaces were most easily generated in the phase diagram to the microemulsion stability region. We study in detail the characteristics of these phases, such as genus per unit surface area per unit volume, and volume fraction occupied by oil water in such a structure. Our discovery calls for new experimental which could be used to discern between bicontinuous and continuous structures. We observe that multiply continuous are most easily generated close to the water-oil coexistence region.
