Diffusive Spin Transport [PDF]
, 2009 Information to be stored and transported requires physical carriers. The quantum bit of information (qubit) can for instance be realised as the spin 1/2 degree of freedom of a massive particle like an electron or as the spin 1 polarisation of a massless photon.

Material barriers to diffusive and stochastic transport [PDF]
Proceedings of the National Academy of Sciences, 2018 Significance Observations of tracer transport in fluids generally reveal highly complex patterns shaped by an intricate network of transport barriers and enhancers. The elements of this network appear to be universal for small diffusivities, independent of the tracer and its initial distribution. Here, we develop a mathematical theory

Quantifying matrix diffusion effect on solute transport in subsurface fractured media [PDF]
Hydrology and Earth System SciencesMatrix diffusion is an important process for solute transport in subsurface fractured media. The effect of matrix diffusion on solute transport depends on various fracture and matrix parameters as well as the underlying temporal-spatial scales.

Deterministic ratchets: Route to diffusive transport [PDF]
Physical Review E, 2002 The rectification efficiency of an underdamped ratchet operated in the adiabatic regime increases according to a scaling current-amplitude curve as the damping constant approaches a critical threshold; below threshold the rectified signal becomes extremely irregular and eventually its time average drops to zero.

Hierarchical simulations of diffusion in zeolites [PDF]
, 2005 The work presented in this chapter involves comparison of simulation and experimental results for intracrystalline and long-range diffusion in zeolitic media in order to demonstrate the hierarchical character of the study of transport in microporous ...

VERIFICATION OF THE DIFFUSION AND TRANSPORT SOLVERS WITHIN DIF3D FOR 3D HEXAGONAL GEOMETRIES [PDF]
EPJ Web of Conferences, 2021 The DIF3D code (DIFfusion 3D) has been a workhorse of fast reactor analysis work at Argonne National Laboratory for over 40 years. DIF3D was primarily built in the late 1970s as a three-dimensional multigroup diffusion equation solver operating on semi ...
