Quasi two-dimensional Fermi surface topography of the delafossite PdRhO
Frank Arnold, Marcel Naumann, Seunghyun Khim +6
We report on a combined study of the de Haas-van Alphen effect and angle resolved photoemission spectroscopy on single crystals of the metallic delafossite PdRhO rounded off by…
On the search for the chiral anomaly in Weyl semimetals: The negative longitudinal magnetoresistance
R. D. dos Reis, M. O. Ajeesh, N. Kumar +6
Recently, the existence of massless chiral (Weyl) fermions has been postulated in a class of semi-metals with a non-trivial energy dispersion.These materials are now commonly dubbe…
Chiral Quasiparticles at the Fermi Surface of the Weyl Semimetal TaAs
Frank Arnold, Marcel Naumann, Shu-Chun Wu +6
Tantalum arsenide is a member of the non-centrosymmetric monopnictides, which are putative Weyl semimetals. In these materials, three-dimensional chiral massless quasiparticles, th…
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…
