The Dynamics of Charge Density Waves
Reviews of Modern Physics, 1985In many materials with a highly anisotropic band structure, electron-phonon interactions lead to a novel type of ground state called the charge-density wave. The condensate is pinned to the underlying lattice by impurities and by boundary effects, but can, even for small electric fields, carry current in a fashion originally envisioned by Fr\"ohlich ...

Observations of charging dynamics
Journal of Geophysical Research: Space Physics, 1983Plasma data from the University of California, San Diego, Auroral Particles experiments on Applied Technology satellites 5 and 6 are used to investigate the dynamics of natural charging events. Both eclipse and daylight charging events are considered, and typical responses are illustrated by data from specific events.

Dynamics of Charge Injection and Charge Recombination in DNA Mini-Hairpins
The Journal of Physical Chemistry B, 2017Steady state spectroscopy, femtosecond transient absorption spectroscopy (fsTA), and femtosecond stimulated Raman spectroscopy (FSRS) of DNA mini-hairpins possessing a diphenylacetylenedicarboxamide (DPA) linker and 1-3 adenine-thymine (A-T) or guanine-cytosine (G-C) base pairs have been investigated.

A Review on Dynamic Wireless Charging Systems
2019 IEEE Milan PowerTech, 2019The increasing diffusion of Electric Vehicles (EVs) is driving academic and institutional research towards exploring different possible ways of charging vehicles in a fast, reliable and safe way. For this reason, Wireless Power Transfer (WPT) systems have recently been receiving a lot of attention in the academic literature.

Dynamics of charge transport in planar devices
Physical Review E, 2008The Poisson-Nernst-Planck equations describe the dynamics of charge transport in an electric field. Although they are relevant in many applications, a general solution is not known and several aspects are not well understood. In many situations nonlinear effects arise for which no analytical description is available. In this work, we investigate charge

The dynamics of colloidal solutions is classically studied in terms of the short-time diffusion coefficient D(q) which is extracted from the first cumulant of the auto-correlation function of the scattered amplitude I(q,t): $$D(q) = - \frac{1}{{{q^2}}}\frac{\partial }{{\partial t}}\log I(q,t = 0).$$ (1)

Abstract A plasma is a mixture of positive ions, electrons and neutral particles, electrically neutral over macroscopic volumes, and usually permeated by macroscopic electrical and magnetic fields. In addition to these ‘smoothed’ or averaged electromagnetic fields, which with laboratory plasmas are often imposed from outside the plasma ...

Theory of charge-density-wave dynamics
Physical Review B, 1988A theoretical model is developed to describe the polarization and depinning of charge-density waves (CDW's) in the inorganic linear-chain compounds which exhibit Fr\"ohlich sliding conduction. Each individual impurity within the crystal is assumed to pin the CDW phase very strongly at the impurity site, and dc CDW motion is made possible only by phase ...

Dynamics of a charged particle in an accelerating field
Il Nuovo Cimento B Series 11, 1989In this paper we study the dynamics of a charged particle in an accelerating field. We make use of a simple perturbation method to derive a general analytic expression of the transfer matrix for the transverse motion. The results have been compared with numerical calculations. In the asymptotic regime,i.e.
