Abstract

A three-dimensional (3D) Dirac semimetal (SM) is the 3D analogue of graphene having linear energy dispersion around Fermi points. Owing to the nontrivial topology of electronic wave functions, the 3D Dirac SM shows nontrivial physical properties and hosts various exotic quantum states such as Weyl SMs and topological insulators under proper external conditions. There are several kinds of Dirac SMs proposed theoretically and partly confirmed experimentally, but its unified picture is still missing. Here we propose a general framework to classify stable 3D Dirac SMs in systems having the time-reversal, inversion and uniaxial rotational symmetries. We show that there are two distinct classes of 3D Dirac SMs. In one class, the Dirac SM possesses a single Dirac point (DP) at a time-reversal invariant momentum on the rotation axis. Whereas the other class of Dirac SMs have a pair of DPs created by band inversion, and carry a quantized topological invariant. Three-dimensional Dirac semimetals are a recently discovered state of condensed matter considered as the 3D analogue of graphene. Here, Yang et al. propose a general framework to classify stable 3D Dirac semimetals in systems with time-reversal, inversion and uniaxial rotational symmetries.

  • A unified treatment of 'band-inverted' and 'symmetry enforced' DSMs can be developed by studying the combined action of time reversal symmetry T, uniaxial rotational symmetry C_n, and inversion symmetry P on a minimal four state Hamiltonian that couples two spin and two orbital degrees of freedom (Gao et al., 2016b; Yang and Nagaosa, 2014).

  • In Class II 3D Dirac semimetals, the location of the 3D Dirac point is fixed either at the center or the edge of the rotation axis, i.e., at a TRIM on the rotation axis.

    “In this Dirac semimetal phase, the location of the 3D Dirac point is fixed either at the center or the edge of the rotation axis, i.e., at a TRIM on the rotation axis.”

  • The bulk Hamiltonian for a Class I DSM on the k_z=0 plane can support a gapped 2D state with nontrivial topology which requires boundary edge modes to occur on this symmetry plane.

    “Nonetheless, as detailed in Table I, the bulk Hamiltonian for a Class I DSM on the k z = 0 plane can support a gapped 2D state with a nontrivial topology which requires boundary edge modes to occur on this symmetry plane (Yang and Nagaosa, 2014).”

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.
