Potato, Banana, Local and Non-Local Transport
The relationship between potato and banana transport theories is addressed using the solution of the drift kinetic equation. It is shown that they are two limits of a complete theory. The potato theory is the ψ → 0 limit and the banana theory is the ψ → ∞ limit. Here, ψ is the poloidal flux function. These local transport theories are valid even in the steep gradient situations because the real...
متن کاملParallel Transport Frame in 4 -dimensional Euclidean Space
In this work, we give parallel transport frame of a curve and we introduce the relations between the frame and Frenet frame of the curve in 4-dimensional Euclidean space. The relation which is well known in Euclidean 3-space is generalized for the rst time in 4-dimensional Euclidean space. Then we obtain the condition for spherical curves using the parallel transport frame of them. The conditi...
متن کاملNon-Local Transport in Turbulent MHD Convection
The nonlocal, non-diiusive transport of passive scalars in turbulent MHD convection is investigated using tran-silient matrices, which describe the "probability" that a tracer particle beginning at one position in a ow will be advected to another position after some time. We present a new method for calculating these matrices from simulation data which involves following the trajectories of pas...
متن کاملLocal fields in non–linear quantum transport
In order to describe frequency-dependent quantum transport properties, it is necessary to take into account local fields. However, since the microscopic charge and current distributions are rapidly varying functions of space and time the solution of Maxwell’s equations is a complex task. Especially in the presence of non–linear effects, a selfconsistent theory of frequency and time dependent tr...
متن کاملLocal Elds in Non{linear Quantum Transport
We investigate the dynamical interplay between currents and electromagnetic elds in frequency-dependent transport through a single-channel quantum wire with an impurity potential in the presence of electron-electron interactions. We introduce and discuss a formalism which allows a self-consistent treatment of currents and electromagnetic elds.
