Directed deterministic classical transport: symmetry breaking and beyond
, 2007 We consider transport properties of a double delta-kicked system, in a regime where all the symmetries (spatial and temporal) that could prevent directed transport are removed.

Pore size estimation from double diffusion encoding
Current Directions in Biomedical Engineering, 2017 Double diffusion encoding is a magnetic resonance technique with applications in measuring microstructure. In many tissues, cell size (which is of a few micrometers) is an important biological parameter.

, 2012 We demonstrate robust and reliable signatures for the transition from quantum to classical behavior in the position probability distribution of a damped double-well system using the Qunatum State Diffusion approach to open quantum systems.

Diffusion and rheology in a model of glassy materials
, 1999 We study self-diffusion within a simple hopping model for glassy materials. (The model is Bouchaud's model of glasses [J.-P. Bouchaud, J. Physique I 2, 1705 (1992)], as extended to describe rheological properties [P. Sollich, F. Lequeux, P. Hebraud and M.

Diffusion thermopower of a serial double quantum dot
New Journal of Physics, 2013 We have experimentally studied the diffusion thermopower of a serial double quantum dot, defined electrostatically in a GaAs/AlGaAs heterostructure. We present the thermopower stability diagram for a temperature difference Δ T = (20 ± 10) mK across the ...

Generalized drift-diffusion model for miniband superlattices
, 2003 A drift-diffusion model of miniband transport in strongly coupled superlattices is derived from the single-miniband Boltzmann-Poisson transport equation with a BGK (Bhatnagar-Gross-Krook) collision term.

Three-dimensional flow of Prandtl fluid with Cattaneo-Christov double diffusion
Results in Physics, 2018 This research paper intends to investigate the 3D flow of Prandtl liquid in the existence of improved heat conduction and mass diffusion models. Flow is created by considering linearly bidirectional stretchable sheet. Thermal and concentration diffusions

Wavefunction considerations for the central spin decoherence problem in a nuclear spin bath
, 2008 Decoherence of a localized electron spin in a solid state material (the ``central spin'' problem) at low temperature is believed to be dominated by interactions with nuclear spins in the lattice.

New-Type Solutions of the Modified Fischer-Kolmogorov Equation
Abstract and Applied Analysis, 2011 We prove the existence of new-type solutions of the modified Fischer-Kolmogorov equation with slow/fast diffusion and with possibly nonsmooth double-well potential.
