Observation of Dirac-like band dispersion in LaAgSb
X. Shi, P. Richard, Kefeng Wang +10
We present a combined angle-resolved photoemission spectroscopy (ARPES) and first-principles calculations study of the electronic structure of LaAgSb in the entire first Brillo…
Observation of Fermi arc spin texture in TaAs
B. Q. Lv, S. Muff, T. Qian +15
We have investigated the spin texture of surface Fermi arcs in the recently discovered Weyl semimetal TaAs using spin- and angle-resolved photoemission spectroscopy. The experiment…
Observation of Weyl nodes and Fermi arcs in TaP
N. Xu, H. M. Weng, B. Q. Lv +18
A Weyl semimetal possesses spin-polarized band-crossings, called Weyl nodes, connected by topological surface arcs. The low-energy excitations near the crossing points behave the s…
Observation of Weyl nodes in TaAs
B. Q. Lv, N. Xu, H. M. Weng +14
In 1929, H. Weyl proposed that the massless solution of Dirac equation represents a pair of new type particles, the so-called Weyl fermions [1]. However the existence of them in pa…
