Thermal composition fluctuations in an ordered lamellar mesophase.
We derive an approximate analytic expression for the structure factor of equilibrium, thermal composition fluctuations in an ordered lamellar mesophase. In order to test the validity of the equation, we perform a series of stochastic simulations using an established model of block copolymer ordering and demonstrate that the equation fits the simulation data with zero adjustable fit parameters over a reasonably wide range of system and simulation parameters.
