Title: Confined complex liquids: Passages, droplets, permanent deformations, and order-disorder transitions
Abstract: A lamellar phase confined between parallel walls changes its structure compared with the bulk system, The system is studied here in the Carlo simulations of the Landau-Ginzburg model of a ternary of oil, water, and surfactant. In the case of strongly boundary conditions at the walls, we observe strong fluctuations in the form of passages. As we change the between the walls we observe the formation of two surfactant then the microemulsion between two layers, and finally four layers. The transition is marked by the peaks in the average characteristic and in its variance. In the case of strongly boundary conditions at one wall and strongly hydrophobic condition at the other, we observe under dilation a permanent of layers in the middle of the system. In the case of weakly boundary conditions, the system exhibits strong topological (passages and droplets) and the lamellar phase which forms perpendicular to the bounding walls. In this case, edge dislocations close to the walls. We also simulate an onion vesicle in a cubic and edge dislocations in slits, and show that the passages appear a dislocation core.
