Evolution of particle separation in slowly decorrelating velocity fields
We consider the evolution of the separation distance between two particles advected by a random velocity field with slowly decaying temporal and spatial correlations in the weak coupling regime. It has been shown in [5] that the motion of a single particle converges to a fractional Brownian motion on a time scale δ−γ with some γ < 2, which is shorter than the classical diffusive time scale δ−2 ...
متن کاملTrap models with slowly decorrelating observables
We study the correlation and response dynamics of trap models of glassy dynamics, considering observables that only partially decorrelate with every jump. This is inspired by recent work on a microscopic realization of such models, which found strikingly simple linear out-of-equilibrium fluctuation-dissipation relations in the limit of slow decorrelation. For the Barrat and Mézard model with it...
متن کاملThe random Schrödinger equation: slowly decorrelating time-dependent potentials
We analyze the weak-coupling limit of the random Schrödinger equation with low frequency initial data and a slowly decorrelating random potential. For the probing signal with a sufficiently long wavelength, we prove a homogenization result, that is, the properly compensated wave field admits a deterministic limit in the “very low” frequency regime. The limit is “anomalous” in the sense that the...
متن کاملTwo-particle dispersion in model two-dimensional velocity fields
We consider two-particle dispersion in a velocity field, where the relative two-point velocity scales according to v(r) ∝ r and the corresponding correlation time scales as τ (r) ∝ r, and fix α = 2/3, as typical for turbulent flows. We show that two generic types of dispersion behavior arize: For α/2+β < 1 the correlations in relative velocities decouple and the diffusion approximation holds. I...
