  • The BDS state can be achieved at the critical point of a topological phase transition between a normal insulator and a TI, requiring fine-tuning of chemical doping/alloying composition.

    “It has also been noted that the BDS state can be achieved at the critical point of a topological phase transition20,21 between a normal insulator and a TI, which requires fine-tuning of the chemical doping/alloying composition thus by effectively varying the spin-orbit coupling strength.”

    From Observation of a three-dimensional topological Dirac semimetal phase in high-mobility Cd3As2 (2014) · cites this paper as [21]

    The electronic-phase discussion (indexed as Abstract; page unavailable) places a bulk-gap closing at approximately x = 0.5, between the topological and non-topological phases of an S/Se alloy. This supports a composition-tuned critical point, but the paper does not establish that the gap closing is a bulk Dirac semimetal (BDS) state or explicitly show that alloying varies spin-orbit coupling strength.

  • In each of these cases, one end member of the series is a topological insulator and the other is a trivial insulator.

    “In each of these cases, one end member of the series is a topological insulator and the other is a trivial insulator.”

  • In TlBiSe2-xSx and Bi2-xInxSe3, evidence of a topological phase transition as a function of x between two phases has been found.

    “This physics has been investigated in both the TlBiSe 2 -x S x (Sato et al. , 2011; Souma et al. , 2012; Xu et al. , 2011b) and Bi 2 -x In x Se 3 (Brahlek et al. , 2012; Wu et al. , 2013), where evidence of topological phase transition as a function of x between two phases have been found.”

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.
