Transport theory for a generic two-arm co-propagating Majorana interferometer with Majorana fermion and edge vortex tunneling
The study investigates transport in a two-arm Majorana interferometer where edge vortices tunnel between arms of a quantum anomalous Hall system. While DC conductance shows no signature of anyon statistics, low-frequency AC conductance reveals an effective capacitance sensitive to the topological spin and conformal dimension of the edge vortices. This effect is measurable at low temperatures using thermal length scales.
