Abstract

An analytical formula for the dc Josephson current in anisotropic singlet superconductor/insulator/anisotropic singlet superconductor junctions is presented. The formula is applicable for junctions with arbitrary insulating-potential height and thickness and with any symmetries including $d$-wave superconductors. In contrast to the formulas for conventional $s$-wave superconductors, the formula includes two additional effects. One is the intrinsic phase of the pair potential originating from the pairing symmetry in anisotropic superconductors. The other is the formation of localized states around the insulator. Using this formula, the Josephson current is calculated in $s$-wave superconductor/insulator/${d}_{{x}^{2}\ensuremath{-}{y}^{2}}$-wave superconductor $(s/I/d)$ and ${d}_{{x}^{2}\ensuremath{-}{y}^{2}}$-wave superconductor/insulator/${d}_{{x}^{2}\ensuremath{-}{y}^{2}}$-wave superconductor $(d/I/d)$ junction configurations. In the case of the $(d/I/d)$ junction, the anomalous temperature dependence of the maximum Josephson current is calculated. This behavior is completely different from that expected for $s$-wave superconductors. The validity of a phenomenological theory by Sigrist and Rice [J. Phys. Soc. Jpn. 61, 4283 (1992)] is also discussed.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
