A pair of researchers at the Hong Kong University of Science and Technology has found that a chiral zero sound (CZS) effect can be induced in Weyl semimetals. In their paper published in the journal Physical Review Letters, ...
Dirac semimetals are critical states of topologically distinct phases. Such gapless topological states have been accomplished by a band-inversion mechanism, in which the Dirac points can be annihilated pairwise by perturbations ...

The 3D Dirac and Weyl semimetals can be characterized by a charge chirality with the parallel or antiparallel locking of electron spin in its momentum. Such materials can exhibit a chiral magnetic effect associated with the ...
Weyl semimetals are topological materials whose low-energy excitations obey the Weyl equation. In a Weyl semimetal, the conduction and valence bands touch at discrete points in momentum space called Weyl nodes. Weyl nodes ...
