Abstract

In the present work, we investigate the source-drain bias spectrum of a hybrid quantum device consisting of a dot-like QPC coupled to an electronic cavity. A singlet-triplet transition manifested as finite-bias anomaly is observed when the cavity is switched on. Besides, we noticed that the 0.7 conductance anomaly is not affected by the cavity, which provides a valuable insight on the origin of the 0.7 conductance anomaly.
