The oscillatory characteristics of magnetoconductance for a junction composed of a superconductor and a semiconductor, in which two parallel quantum wave guides are coupled with each other through a potential barrier layer, are studied systematically. To model the imperfectness of the interface,...

We investigate mesoscopic spin transport through a quantum dot (QD) responded by a rotating and an oscillating magnetic fields. The rotating magnetic field rotates with the angular frequency ω0 around the z-axis with the tilt angle θ, while the time-oscillating magnetic field is located in the...

We have investigated the shot noise affected by the perturbation of two microwave fields (MWFs) with frequencies ω<Subscript>1</Subscript> and ω<Subscript>2</Subscript>, which can be classified as the commensurate and incommensurate external ac fields. The time-dependent current correlation function and the spectral density of shot noise...</subscript></subscript>
