Topological semimetals (TSMs) are characterized by bulk band crossings in their electronic
structures, which are expected to give rise to gapless electronic excitations and topological …

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 …

Weyl semimetals provide the realization of Weyl fermions in solid-state physics. Among all
the physical phenomena that are enabled by Weyl semimetals, the chiral anomaly is the …

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

Since their discovery, topological insulators are expected to be ideal spintronic materials
owing to the spin currents carried by surface states with spin-momentum locking. However …

Topological Dirac semimetal is a newly discovered class of materials which has attracted
intense attention. This material can be viewed as a three-dimensional (3D) analog of …

The quantum Hall effect is usually observed in 2D systems. We show that the Fermi arcs can
give rise to a distinctive 3D quantum Hall effect in topological semimetals. Because of the …

The topological semimetal is a new, theoretically predicted and experimentally discovered,
topological state of matter. In one of its several realizations, the topological semimetal hosts …

Astrophysical black hole candidates, although long thought to have a horizon, could be
horizonless ultracompact objects. This intriguing possibility is motivated by the black hole …

Anisotropic magnetoresistance is the change tendency of resistance of a material on the
mutual orientation of the electric current and the external magnetic field. Here, we report …
