Mean-Field Approach to Finite-Size Fluctuations in the Kuramoto-Sakaguchi Model

Author(s): Oleh E. Omel’chenko and Georg A. Gottwald We develop an ab initio approach to describe the statistical behavior of finite-size fluctuations in the deterministic Kuramoto-Sakaguchi model. We obtain explicit expressions for the covariance function of fluctuations of the complex order parameter and determine the variance of its magnitude entir… [Phys. Rev.
