Conductance of a junction between a normal metal and a Berezinskii superconductor
PACS: 74.20.Rp, 74.25.Fy, 74.45.+c, 74.50.+r
The conductance of a junction between a normal metal and a superconductor having the symmetry proposed by Berezinskii is studied theoretically. The main feature of this symmetry is the odd frequency dependence of the anomalous Green function, which makes possible the s-wave triplet superconducting state (the Berezinskii superconductor). The Andreev reflection (which links positive and negative energies) is sensitive to the energetic symmetry; as a result, the conductance of the junction involving the Berezinskii superconductor is qualitatively different from the case of a conventional superconductor. Experimentally, the obtained results can be employed to test the possibility of the Berezinskii superconductivity proposed for NaxCoO2 and to identify the odd-ω component predicted for superconductor-ferromagnet systems.
