Late Time Correlations in Hydrodynamics: Beyond Constitutive Relations
Late Time Correlations in Hydrodynamics: Beyond Constitutive Relations
We investigate the effects of nonlinear stochastic interactions on hydrodynamic response functions. The interactions are parametrized by "stochastic transport coefficients" that are invisible in the classical constitutive relations, but nonetheless affect the late time hydrodynamic correlations. We present a classification scheme for such coefficients that applies beyond the naive stochastic …
