Tunneling current through Tomonaga-Luttinger liquid ring with spin-orbit coupling — •Mikhail Pletyukhov¹, Nicolas Pauget¹, and Vladimir Gritsev² — ¹Institut für Theoretische Festkörperphysik, Universität Karlsruhe, D-76128 Germany — ²Department of Physics, Harvard University, Cambridge, MA 02138, USA

We calculate dc conductance of an interacting quantum ring with spin-orbit coupling which is attached to normal leads. We consider the linear response regime and assume a weak coupling to the leads. Electron-electron interaction in the ring is described non-perturbatively by means of the multicomponent Tomonaga-Luttinger liquid model. We study how the positions of the conductance peaks depend on the system parameters (magnetic flux, gate voltage, spin-orbit coupling strength) and observe the features arising due to electron correlations.
