We theoretically study the effects of interaction of the single electron confined in a piece of bilayer nanowire with the picosecond magnetic pulse. It is shown that the transverse time-varying magnetic field hybridizes temporarily the vertical modes in the electron wave function which eventually stimulates its motion along the wire axis. The dynamics of such magnetically driven motion depends on the geometry of the confining potential, the effective mass of the electron and the time duration of the magnetic pulse. We show that this effect can potentially be utilized for fabrication of the magnetic valve.

A theoretical study of two-particle systems in quasi-one-dimensional quantum wires and quantum dots is presented. We have derived the analytical formula for the effective interaction potential between the charge carriers confined laterally by a strong parabolic potential and applied this formula to electron pairs in single and double quantum dots and to excitons in quantum wires. In the single quantum dot of the sufficiently large size, we have found the Wigner-type localization.
