Abstract
The tunnel conductance in normal-metal/Na{sub x}CoO{sub 2} is studied theoretically, where NaCoO{sub 2} is a new superconductor discovered in a recent experiment. So far, it has been pointed out that superconductivity is characterized by an unconventional pairing symmetry and that the chiral symmetry may be broken down in the superconducting phase of Na{sub x}CoO{sub 2}. Theoretical studies have suggested p, d and f wave pairing symmetries. We calculate the differential conductance of Na{sub x}CoO{sub 2} within the quasiclassical approximation by assuming the chiral p, chiral d and f wave symmetries. The results show the zero-bias conductance peak in the case of p and f wave symmetries in tunnel spectra.
