Pb1-xSnxTe has an insulator-to-metal transition at approximately 12 kbar that is believed to be a band closing transition at the L points; the metallic phase is stable until about 25 kbar and is reasonably interpreted as an intermediate Weyl phase occurring between topological and trivial regimes.
“Pb 1 -x Sn x Te has an insulator-to-metal transition at approximately 12 kbar that is believed to be a band closing transition occurring at the L points of the Brillouin Zone. The metallic phase is stable until about 25 kbar and is reasonably interpreted as an intermediate Weyl phase occurring between topological and trivial regimes (Liang et al. , 2017).”

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.
