摘要
We develop a concept of frustrating charges to create a theory of self-assembly. In particular, we note that the constraints of stoichiometry frustrate ordinary phase equilibria and lead to self-assembly of systems such as oil-water-surfactant mixtures. Further we note that at long wavelengths, the constraints of stoichiometry are isomorphic to the constraints of charge neutrality in a specific electrostatic analogy. We expand upon this analogy, first noted by Stillinger, and show that it can be used to derive useful analytical estimates. In addition we use the analogy to create a new model for frustrated systems, and we present Monte Carlo results for this charge frustrated Ising system that exhibits varied behaviors of self-assembly. The Monte Carlo calculations are made possible through the development of an algorithm which permits cluster moves.
