Negative magnetoresistance without well-defined chirality in the Weyl semimetal TaP

Frank Arnold, Chandra Shekhar, Shu-Chun Wu +15

Weyl semimetals (WSMs) are topological quantum states wherein the electronic bands linearly disperse around pairs of nodes, the Weyl points, of fixed (left or right) chirality. The…
