We predict that pure spin current flowing through the transverse leads of quantumcoherent two-dimensional electron gas (2DEG), which is induced by conventional unpolarized charge current driven through the longitudinal leads, can be tuned by the Rashba spin-orbit (SO) interaction and will decay only when disorder is sufficiently strong (but before electrons become localized). Furthermore, the p...
In this paper we study the integer quantum Hall effect (IQHE) on the systems with different types of impurities in delta and gaussian forms. The Landau energy levels in the presence of impurity split in two different levels,the extended and localized levels, emerging then the Hall step. Finally, we add a specified form of a quantum dot potential to a system with impurity, and observed that incr...
Edge states of the quantum Hall fluid provide an opportunity to study mesoscopic effects in a highly correlated electron system that is both experimentally accessible and theoretically tractable. In this paper we review recent work on the persistent current and Aharonov-Bohm magnetoconductance oscillations in the fractional quantum Hall effect regime.
