Mesoscopic transport properties of multiterminal Coulomb Majorana junctions
In this talk, the low-energy quantum transport properties of the Coulomb-Majorana junction will be discussed, where several helical nanowires are coupled to a joint mesoscopic superconductor with finite charging energy. By virtue of the proximity effect, Majorana bound states are formed near the ends of the superconducting wire parts, which are coupled together by charging effects. For sufficiently weak but finite charging energy, this system generically approaches an isotropic SO(M) Kondo fixed point with non-Fermi liquid behavior observable in quantum transport observables such as the temperature-dependent conductance tensor or the fluctuating current noise correlator. The latter quantities follow from the Keldysh formulation of an effective phase action approach.
