Coulomb interaction-induced Aharonov-Bohm oscillations
Toshihiro Kubo ; Yasuhiro Tokura ;
Date 2 Aug 2015
AbstractWe study the Coulomb interaction-induced Aharonov-Bohm (AB) oscillations in the linear response transport through a remote quantum dot which has no tunnel coupling but has Coulomb coupling with the quantum dot embedded in an AB interferometer. We show that the Coulomb interaction-induced AB effect is characterized by a charge susceptibility of a remote quantum dot in a weak interaction regime. In a strong but finite interaction regime, around the particle-hole symmetric point, there exists the region where the visibility of the induced AB oscillations becomes one although the visibility of the original AB oscillations in the interferometer is low.
