Abstract

We discuss the proximity effect of spin-triplet superconductors on electric conductance of remote current by using the quasiclassical Green function method. Conductance spectra show a zero-bias anomaly, which reflects enhancement of quasiparticle density of states at the Fermi energy in a normal metal. Odd-frequency symmetry of Cooper pairs in a normal metal is responsible for the zero-bias anomaly.
