Anomalous transport is ever-present in many disordered organic semiconductor materials. The long-tail behavior observed in the transient photocurrent is a manifestation of anomalous transport. Owing to the fact that anomalous transport has dispersive and non-Gaussian transport dynamics, thus anomalous transport cannot be adequately described by the standard drift-diffusion equation which is a f...

In the presence of dense matter quantum anomalies give rise to two new transport phenomena. An anomalous current is generated either by an external magnetic field or through vortices in the fluid carrying the anomalous charge. The associated transport coefficients are the anomalous magnetic and vortical conductivities. Whereas a Kubo formula for the anomalous magnetic conductivity is well known...

The emergence of scaling in transport through interconnected systems is a consequence of the topological structure of the network and the physical mechanisms underlying the transport dynamics. We study transport by advection and diffusion in scale-free and Erdős-Rényi networks. Velocity distributions derived from a flow potential exhibit power-law scaling with exponent ν≈γ+1, where γ is the exp...

In edge plasmas, such as the tokamak scrape-off layer, transport parallel and perpendicular to the magnetic field are strongly coupled. It is shown that this leads to an unconventional form of the parallel transport laws. In particular, if the radial transport is governed by anomalous diffusion, the parallel ion transport cannot be entirely classical. This general phenomenon is demonstrated exp...

We study the nature of non-Fickian particle transport in 3-D porous media by simulating fluid flow in the intricate pore space of real rock. We solve the full Navier-Stokes equations at the same resolution as the 3-D micro-CT (computed tomography) image of the rock sample and simulate particle transport along the streamlines of the velocity field. We find that transport at the pore scale is mar...

The discovery of anomalous diffusion of larger biopolymers and submicron tracers such as endogenous granules, organelles, or virus capsids in living cells, attributed to the viscoelastic nature of the cytoplasm, provokes the question whether this complex environment equally impacts the active intracellular transport of submicron cargos by molecular motors such as kinesins: does the passive anom...

Recently, both Alcator C-Mod and DIII-D tokamaks observed fast anomalous cross-field plasma transport in the SOL. These observations supported by theoretical studies have indicated that such transport is essentially non-diffusive and intermittent. We present the results of macroscopic plasma simulations with the UEDGE transport code including anomalous cross-field outward-directed convection fo...

[1] Surface transports into the California Current are calculated from TOPEX/POSEIDON altimeter surface height slopes during the 9.5 year period from October 1992–May 2002. These quantify the anomalous onshore and southward displacements of the water column during the 2000–2002 period, which had been hypothesized by others based on anomalous water properties observed in mid-2002 off Oregon. Ano...

Anomalous transport of heat and particles is known to be a key issue for fusion devices. In the present paper the anomalous transport of fast ions is investigated. High transit frequencies of the fast ions lead to the assumption that there is only very weak interaction with the low-frequency turbulence. However, our results indicate a significant fast ion particle transport due to the turbulenc...

The Mott relation between the electrical and thermoelectric transport coefficients normally holds for phenomena involving scattering. However, the anomalous Hall effect (AHE) in ferromagnets may arise from intrinsic spin-orbit interaction. In this work, we have simultaneously measured AHE and the anomalous Nernst effect (ANE) in Ga1-xMnxAs ferromagnetic semiconductor films, and observed an exce...
