Tunneling effect of chiral triplet superconductors

The differential conductance in normal metal/Sr2RuO4 superconducting junctions is theoretically studied. We consider three types of chiral p-wave symmetries in ruthenate such as kx+iky, sin(kx)+i sin(ky) and sin(kx+ky)+i sin(kx−ky). Contrary to the first simple pair potential, the conductance for the second and the third pair potentials do not always have a zero bias conductance peak. In addition, the conductance line shapes depend seriously on the misorientation angles of junctions and the shape of the Fermi surface.
