The combination of superconductivity and topology is expected to display novel quasiparticles, including non-Abelian Majorana zero modes or fractional charge and spin currents.
“The combination of superconductivity and topology is expected to display novel types of quasiparticles, including non-Abelian Majorana zero modes or fractional charge and spin currents 90 -92 .”
From Recent advances in high-entropy superconductors (2024) · cites this paper as [92]
The paper’s main text predicts fractional charge at magnetic domain walls in a quantum spin Hall insulator and a quantized charge current driven by a rotating magnetic field (page unavailable). It does not attribute these effects to a combination of superconductivity and topology, or describe non-Abelian Majorana zero modes or fractional spin currents. Thus it supports the fractional-charge example, but not the broader claim as attributed to this source. (LLM, conf=0.87)

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.
