The one– and two– particle densities of up to four interacting electrons with spin, confined within a quasi one–dimensional “quantum dot” are calculated by numerical diagonalization. The transition from a dense homogeneous charge distribution to a dilute localized Wigner–type electron arrangement is investigated. The influence of the long range part of the Coulomb interaction is studied. When t...
According to Newton’s law of gravity, two masses interact with each other via a central force which can be derived from the potential VN (r) = −Gm1m2/r where G is a universal constant known as Newton’s constant. Likewise, according to Coulomb’s law, two electrically charged particles with charges n1e and n2e interact via the central potential VCb (r) = αn1n2/r where e is the elementary charge a...
Ultrahigh spectral brightness femtosecond XUV and X-ray sources like free electron lasers (FEL) and table-top high harmonics sources (HHG) offer fascinating experimental possibilities for analysis of transient states and ultrafast electron dynamics. For electron spectroscopy experiments using illumination from such sources, the ultrashort high-charge electron bunches experience strong space-cha...
We demonstrate theoretically that a charge current and a spin current are generated by spin dynamics in the presence of spin-orbit interaction in the perturbative regime. We consider a general spin-orbit interaction including the spatially inhomogeneous case. Spin current due to spin damping is identified as one origin of generated charge current, but other contributions exist, such as the one ...
