Mesoscopic superconductivity: Josephson current through spin-polarized luttinger liquid

Nobuhiko Yokoshi, Susumu Kurihara

    Research output: Chapter in Book/Report/Conference proceedingChapter


    Josephson current through a Luttinger liquid (LL) under a magnetic field is theoretically studied. We derive an analytical expression of Josephson current for clean interfaces, by using quasiclassical Green’s function and functional bosonization procedure. Because of spin-dependent energy shift in Andreev bound states, current-phase relations acquire positive slopes at phase difference x=π (π-state). Renormalization of the critical current, due to electron-electron interactions, is found. Further, we show that repulsive interactions detabilize the π-state, while attractive ones stabilize.
