摘要：

It is shown that the presence of the continuum of Majorana fermion edge states along the perimeter of a chiral topological superconductor can be probed using an interacting quantum dot coupled to three terminals: the lead supporting the Majorana edge states and two spin-polarized (ferromagnetic) measurement leads. The hybridization with the Majorana states induces a particular type of the Kondo effect with non-Fermi-liquid properties which can be detected by performing linear conductance measurements between the source and drain measurement leads: the temperature and magnetic-field dependence of the conductance is characteristically different from that in the conventional Kondo effect.
