Coulomb interaction-induced Aharonov-Bohm oscillations | Toshihiro Kubo

2 Aug 2015 | Abstract: | We 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. | Source: | arXiv, 1508.0214 | Services: | Forum | Review | PDF | Favorites |
