Abstract

We have studied the resonance patterns on the Hall and the nonlocal resistances in an H shaped quantum wire conductor with and without a magnetic field. We have found that the resonance patterns on the Hall resistance can be explained by usual multiple reflections of electron waves in a bridge-like portion of the H structure. However, we have found that the resonance patterns on the nonlocal resistance are mainly caused by inter-mode transitions of two highest modes in the system, which yield large oscillations in a mixing frequency in the resistance curve with respect to all the physical variables we have considered, such as the Fermi energy and the magnetic field. Due to largeness of the period of the nonlocal oscillations, we propose that the nonlocal resistance is a better candidate for observation of resonance in real experimental settings.
