Abstract (English)

Spin-dependent electronic transport properties of mesoscopic systems are studied using the nonequilibrium Green function formalism. In the first part we examine the influence of short-range electron-electron interactions on the conductance of quantum point contacts, where the 0.7 anomaly is frequently observed in experiments. The repulsion between electrons with opposite spins causes a ...

Spinabhängige elektronische Transporteigenschaften mesoskopischer Systeme werden mithilfe des Nichtgleichgewichts-Greensfunktionsformalismus untersucht. Im ersten Teil untersuchen wir den Einfluss kurzreichweitiger Elektron-Elektron Wechselwirkungen auf den Leitwert von Quantenpunktkontakten, wo in Experimenten häufig die 0.7-Anomalie beobachtet wird. Die Abstoßung von Elektronen ...
