Dirac semimetal in three dimensions.
We show that the pseudorelativistic physics of graphene near the Fermi level can be extended to three dimensional (3D) materials. Unlike in phase transitions from inversion symmetric topological to normal insulators, we show that particular space groups also allow 3D Dirac points as symmetry protected degeneracies. We provide criteria necessary to identify these groups and, as an example, prese...
متن کاملNegative magnetoresistance in Dirac semimetal Cd3As2
A large negative magnetoresistance (NMR) is anticipated in topological semimetals in parallel magnetic fields, demonstrating the chiral anomaly, a long-sought high-energy-physics effect, in solid-state systems. Recent experiments reveal that the Dirac semimetal Cd3As2 has the record-high mobility and positive linear magnetoresistance in perpendicular magnetic fields. However, the NMR has not ye...
متن کاملEvidence of Topological Surface State in Three-Dimensional Dirac Semimetal Cd3As2
The three-dimensional topological semimetals represent a new quantum state of matter. Distinct from the surface state in the topological insulators that exhibits linear dispersion in two-dimensional momentum plane, the three-dimensional semimetals host bulk band dispersions linearly along all directions. In addition to the gapless points in the bulk, the three-dimensional Weyl/Dirac semimetals ...
متن کاملDirac semimetal thin films in in-plane magnetic fields
In this work we study the effects of in-plane magnetic fields on thin films of the Dirac Semimetal (DSM) Na3Bi where one of the in-plane directions is perpendicular to the k-separation between the two Weyl nodes that exist for each spin orientation. We show numerically that the states localized near the surfaces of these thin films are related to the Fermi arc states in semi-infinite slabs. Due...
متن کاملPhenomenology of a semi-Dirac semi-Weyl semimetal
We extend the semiclassical study of fermionic particle-hole symmetric semi-Dirac (more appropriately, semiDirac semi-Weyl) dispersion of quasiparticles, εK = ± √ (k2 x/2m) + (vky)) = ±ε0 √ K4 x +K2 y in dimensionless units, discovered computationally in oxide heterostructures by Pardo and collaborators. This unique system is a highly anisotropic sister phase of both (symmetric) graphene and wh...
