In the semiclassical EOM: v=\frac{\partial \mathcal E}{\hbar \partial k}-\dot k\times \Omega(k),\quad \dot k=-eE-ev\times B Here, \Omega is the Berry curvature (corresponds to anomalous velocity) and \hbar k is the "gauge invariant or mechanical crystal momentum": \hbar k=\...
The spin is the property of the electron whereby it has an intrinsic angular momentum in addition to the angular momentum of its orbital motion. The spin magnetization is denoted by ms and the volume density of spin magnetization is denoted by Ms. The volume density of spin magnetization M =...
In order to separate valence and core electron charge densities, one needs an electron probe size that is much smaller than the 1 Å feature size of valence electron orbitals. Achieving this experimentally is currently challenging as state-of-the-art probes are on the order of valence electr...
Persistent luminescence, long-lived emission from inorganic or organic materials after the cessation of excitation, receives considerable attention in the field of optoelectronics. Despite great achievements in the past decades, the performance of organi
The present paper reports an analysis of the electron-spin-resonance (ESR) line observed in electron-bombarded polymer electrets after annealing. It is sho... M Legrand,G Dreyfus,J Lewiner - 《Physical Review B》 被引量: 8发表: 1979年 Ion Impacts and Nanostructures on Ge(111), In0.22Ga...
The most prominent example of memory based on a strong electron donor and an acceptor compound, which forms a charge transfer state, are thin films consisting of Cu+TCNQ−. A typical memory element with its current versus voltage characteristic is shown in Fig. 48. The device shows two stab...
The Integrable Optics Test Accelerator at Fermilab will explore beam dynamics in a ring with intense space-charge using 2.5 MeV proton beams with an incoherent tune shift approaching -0.5. We will use this machine to explore the interplay between electron cooling, intense space-charge, and coherent...
One- and two-step double-electron capture in slow Ar6+-He collisions Double-electron capture by slow (15--30 eV/u) Arions from He has been studied by simultaneous measurements of postcollisional projectile energy-gain and an... LR Andersson,H Cederquist,A Barany,... - 《Physical Review ...

In this Review, we investigate the spatially inhomogeneous signatures of charge flow in conductors, with particular emphasis on the recently rekindled field of electron hydrodynamics,...
(3D) plasmons, which reflect the nature of the electronic structure and Coulomb repulsion on both short and long lengthscales. With increasing electron doping, the plasmon excitations increase monotonically in energy, a consequence of the electron correlation effect on electron structure near the Fermi...
