摘要：

We discuss the minimum value of the zero-bias differential conductance in a normal-metal/unconventional-superconductor junction. A numerical simulation demonstrates that the zero-bias conductance is quantized at in the limit of strong impurity scatterings in the normal-metal. The integer represents the number of perfect transmission channels through the junction. By focusing on the chiral symmetry of Hamiltonian, we prove the existence of -fold degenerate resonant states in the dirty normal segment.
