Abstract: We show that, for systems described by non-linear first- and second-order Langevin equations, the high-frequency correlations always have respectively, an ω−2 and ω−4 asymptotic behavior, irrespective of the shape and strength of the non-linearities, and whether detailed balance is obeyed in the stationary state or not.
