Weyl and Dirac semimetals are three-dimensional phases of matter with gapless electronic
excitations that are protected by topology and symmetry. As three-dimensional analogs of …

Topological semimetals are well known for the linear energy band dispersion in the bulk
state and topologically protected surface state with arc-like Fermi surface. The angle …

Abstract Two-dimensional (2D) materials 1, 2, 3, 4, 5 offer a unique platform from which to
explore the physics of topology and many-body phenomena. New properties can be …

Recent experiments have revealed spectacular transport properties in semimetals, such as
the large, non-saturating magnetoresistance exhibited by WTe2 (ref.). Topological …

A large negative magnetoresistance (NMR) is anticipated in topological semimetals in
parallel magnetic fields, demonstrating the chiral anomaly, a long-sought high-energy …

Cd 3 As 2 is a candidate three-dimensional Dirac semimetal which has exceedingly high
mobility and nonsaturating linear magnetoresistance that may be relevant for future practical …

The most recognizable feature of graphene's electronic spectrum is its Dirac point, around
which interesting phenomena tend to cluster. At low temperatures, the intrinsic behaviour in …

Topological insulators, a new class of condensed matter having bulk insulating states and
gapless metallic surface states, have demonstrated fascinating quantum effects. However …

Despite much theoretical effort, there is no complete theory of the “strange” metal state of the
high temperature superconductors, and its linear-in-temperature T resistivity. Recent …

We investigated the magnetoresistive behavior of an ideal Dirac semimetal—high-quality
single crystals of Cd 3 As 2 with a Fermi level very close to the Dirac point. A large linear …
