From ballistic to diffusive behavior in periodic potentials
The long-time/large-scale, small-friction asymptotic for the one dimensional Langevin equation with a periodic potential is studied in this paper. It is shown that the FreidlinWentzell and central limit theorem (homogenization) limits commute. We prove that, in the combined small friction, long-time/large-scale limit the particle position converges weakly to a Brownian motion with a singular di...
متن کاملCrossover from Diffusive to Ballistic Transport in Periodic Quantum Maps
We derive an expression for the mean square displacement of a particle whose motion is governed by a uniform, periodic, quantum multi-baker map. The expression is a function of both time, t, and Planck’s constant, ~, and allows a study of both the long time, t → ∞, and semi-classical, ~ → 0, limits taken in either order. We evaluate the expression using random matrix theory as well as numerical...
متن کاملDiffusive Transport in Periodic Potentials: Underdamped Dynamics
In this paper we present a systematic and rigorous method for calculating the diffusion tensor for a Brownian particle moving in a periodic potential which is valid in arbitrary dimensions and for all values of the dissipation. We use this method to obtain an explicit formula for the diffusion coefficient in one dimension which is valid in the underdamped limit, and we also obtain higher order ...
متن کاملCrossover from Ballistic to Diffusive Thermal Transport in Carbon Nanotubes
We present a theoretical scheme that seamlessly handles the crossover from fully ballistic to diffusive thermal transport regimes and apply it to carbon nanotubes. At room temperature, the micrometer-length nanotubes belong to the intermediate regime in which ballistic and diffusive phonons coexist, and the thermal conductance exhibits anomalous nonlinear tube-length dependence due to this coex...
متن کاملInteraction-induced magnetoresistance: from the diffusive to the ballistic regime.
We study interaction-induced quantum correction deltasigma(alphabeta) to the conductivity tensor of electrons in two dimensions for arbitrary Ttau, where T is the temperature and tau the transport mean free time. A general formula is derived, expressing deltasigma(alphabeta) in terms of classical propagators ("ballistic diffusons"). The formalism is used to calculate the interaction contributio...
