The electron structure functions are studied in polarized $e^+e^-$ scattering. The formulae for longitudinally and transversely polarized electrons are presented. The smallnes of the electron mass leads to negligible cross-sections and…

We argue that in the ensemble Monte Carlo approach, the spin decoherence caused by electron-electron interactions in n-type bulk GaAs at room temperature, according to Dyakonov-Perel theory, is mainly induced by the electron density while…

The conductance of a weakly interacting electron gas in the presense of a single scatterer is found at arbitrary strength of the scattering potential. At weak interaction, a simple renormalization group approach can be used instead of the…
