a Differential conductance of the injector junction (Ginj) as a function of injector voltage (Vinj) and magnetic field (H), and horizontal slices at H = 0 T and H = 1 T (black traces). The quasiparticle density of states in the superconducting wire can be seen to be clearly Zeeman split at 1 T. b Differential conductance of the detector junction (\({G}_{\det }\)) as a function of the detector voltage (\({V}_{\det }\)) at H = 1 T without any injection current. As the detector is not Zeeman-split, we also see the Zeeman splitting of the quasiparticle density of states in the superconducting wire.
