  The chiral topological superconductor, which supports propagating nontrivial
edge modes while maintaining a gapped bulk, can be realized hybridizing a
quantum-anomalous-Hall thin slab with an ordinary $s$-wave superconductor. We
show that by sweeping the voltage bias in a normal-hybrid-normal double
junction, the pattern of electric currents in the normal leads spans three main
regimes. From single-mode edge-current quantization at low bias, to double-mode
edge-current oscillations at intermediate voltages and up to diffusive bulk
currents at larger voltages. Observing such patterns by resolving the spatial
distribution of the local current in the thin slab could provide additional
evidence, besides the global conductance, on the physics of chiral topological
superconductors.
