Tunneling current in triplet f-wave superconductors with horizontal lines of nodes

Abstract

We calculate the tunneling conductance spectra of a normal-metal/insulator/triplet superconductor using the Blonder-Tinkham-Klapwijk (BTK) formulation. Possible states for the superconductor are considered with horizontal lines of nodes, breaking the time reversal symmetry. These results would be useful to discriminate between pairing states in superonductor Sr${}_2$RuO${}_4$ and also in UPt${}_3$.
