Role of bias and tunneling asymmetries in nonlinear Fermi-liquid transport through an SU($N$) quantum dot

Kazuhiko Tsutsumi, Yoshimichi Teratani, Kaiji Motoyama +2

We study how bias and tunneling asymmetries affect nonlinear current through a quantum dot with $N$ discrete levels in the Fermi liquid regime, using an exact low-energy expansion…
