Time dependent convection electric fields and plasma injection

Dynamics of Berry-phase polarization in time-dependent electric fields

We consider the flow of polarization current J5dP/dt produced by a homogeneous electric field E(t) or by rapidly varying some other parameter in the Hamiltonian of a solid. For an initially insulating system and a collisionless time evolution, the dynamic polarization P(t) is given by a nonadiabatic version of the KingSmith–Vanderbilt geometric-phase formula. This leads to a computationally con...

Electric field-induced plasma convection in tokamak divertors

Measurements of the electric fields, E in the DIII-D tokamak divertor region @J. C. Luxon and L. G. Davis, Fusion Technology 8, Part 2A, 441 ~1985!# are quantitatively consistent with recent computational modeling establishing that E3BT circulation is the main cause of changes in divertor plasmas with the direction of the toroidal magnetic field, BT . Extensive two-dimensional measurements of p...

Kinetics of Parton- Antiparton Plasma Vacuum Creation in the Time - Dependent Chromo - Electric Fields of Arbitrary Polarization

The kinetic equation of non Markovian type for description of the vacuum creation of parton antiparton pairs under action of a space homogeneous time dependent chromo electric field of the arbitrary polarization is obtained on the strict non pertubative foundation in the framework of the oscillator representation. A comparison of the effectiveness of vacuum creation with the case of linear pola...

Wave function for harmonically confined electrons in time-dependent electric and magnetostatic fields.

We derive via the interaction "representation" the many-body wave function for harmonically confined electrons in the presence of a magnetostatic field and perturbed by a spatially homogeneous time-dependent electric field-the Generalized Kohn Theorem (GKT) wave function. In the absence of the harmonic confinement - the uniform electron gas - the GKT wave function reduces to the Kohn Theorem wa...
