The Anomalous Transport in Plasmas
1. Overview The main research topics for this year have been organized in nine milestones with theoretical and experimental relevance: 1. Influence of the collisions in the gyrokinetic simulations on the particle transport 2. Characterization of the intermittent events and particle transport on the plasma boundary 3. Characterization of long-range correlations and multi-scale physics in L-mode ...
متن کاملAnomalous edge transport in the quantum anomalous Hall state.
We predict by first-principles calculations that thin films of a Cr-doped (Bi,Sb)2Te3 magnetic topological insulator have gapless nonchiral edge states coexisting with the chiral edge state. Such gapless nonchiral states are not immune to backscattering, which would explain dissipative transport in the quantum anomalous Hall (QAH) state observed in this system experimentally. Here, we study the...
متن کاملAnomalous Transport in Disordered Dynamical Systems
We consider simple extended dynamical systems with quenched disorder. It is shown that these systems exhibit anomalous transport properties such as the total suppression of chaotic diffusion and anomalous drift. The relation to random walks in random environments, in particular to the Sinai model, explains also the occurence of ageing in such dynamical systems. Anomalous transport is explained ...
متن کاملAnomalous energy transport in FPU-β chain
This paper is devoted to the derivation of a macroscopic diffusion equation (Fourier’s law) describing the transport of energy in an anharmonic chain. More precisely, we study here the so-called FPU-β chain, which is a very simple model for a one-dimensional crystal in which atoms are coupled to their nearest neighbors by a harmonic potential, weakly perturbed by a quartic potential. The starti...
متن کاملAnomalous transport in conical granular piles.
Experiments on 2+1-dimensional piles of elongated particles are performed. Comparison with previous experiments in 1+1 dimensions shows that the addition of one extra dimension to the dynamics changes completely the avalanche properties, with the appearance of a characteristic avalanche size. Nevertheless, the time which single grains need to cross the whole pile varies smoothly between several...
