Hamiltonian and Brownian systems with long-range interactions: V. Stochastic kinetic equations and theory of fluctuations


We develop a theory of fluctuations for Brownian systems with weak long-range interactions. For these systems, there exists a critical point separating a homogeneous phase from an inhomogeneous phase. Starting from the stochastic Smoluchowski equation governing the evolution of the fluctuating density field of the Brownian particles, we determine the… (More)
