Conductance of a junction between a normal metal and a Berezinskii superconductor
Ya. V. Fominov L. D. Landau Institute for Theoretical Physics, Russian Academy of Sciences
Abstract:
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 \textit 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 $\mathrm{Na_xCoO_2}$ and to identify the odd-$\omega$ component predicted for superconductor-ferromagnet systems.
