Magnetic resonance in a singlet-triplet Josephson junction

Abstract

We study a singlet-triplet Josephson junction between a conventional s-wave superconductor and an unconventional p${}_{\mathrm{x}}$-wave superconductor. The Andreev spectrum of the junction yields a spontaneous magnetization in equilibrium. This allows manipulating the occupation of the Andreev levels using an ac Zeeman field. The induced Rabi oscillations manifest themselves as a resonance in the current-phase relation. For a circularly polarized magnetic field, we find a spin selection rule, yielding Rabi oscillations only in a certain interval of the superconducting phase difference.
