On edge states in superconductors with time inversion symmetry breaking
Open accessAbstract
Superconducting states with different internal topology are discussed for the layered high-T c materials. If the time inversion symmetry is broken, the superconductivity is determined not only by the symmetry of the superconducting state but also by the topology of the ground state. The latter is determined by the integer-valued momentum-space topological invariant N. The current carrying boundary between domains with different N (N 2≠N 1) is considered. The current is produced by fermion zero modes, the number of which per layer is 2(N 2−2N 1).

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.
