I will discuss a problem of energy-driven pattern formation, in which the appearance of two distinct phases caused by short-range attractive forces is frustrated by a long-range repulsive force. I will focus on the regime of strong compositional asymmetry, in which one of the phases has very small volume fraction, thus creating small “droplets” of the minority phase in a “sea” of the majority phase. I will present a setting for the study of Gamma-convergence of the governing energy functional in the regime leading to many droplets.

Abstract: A modeling and simulation formalism is presented for the study of soft materials. The formalism
takes into account microstructure elasticity, hydrodynamic interactions, and thermal fluctuations. As a specific motivation we consider lipid bilayer membranes and polymeric fluids. The
approach couples a Lagrangian description of the microstructures (lipid molecules / polymers)
