摘要：
We investigate the quantum transport phenomena for a quasi-one-dimensional quantum wire with antidots in magnetic fields. The calculated magnetoconductance shows a quasi-periodic structure of the group of dips. The characteristic properties of the magnetoconductance can be understood through a simple hopping model, where the electron transfers between the neighboring pinned orbits. We also discuss the interference effects on the conductance in connection with local electronic states.
