Nodeless superconductivity in noncentrosymmetric PbTaSe single crystals
G. M. Pang, M. Smidman, L. X. Zhao +7
We report an investigation of the superconducting order parameter of the noncentrosymmetric compound PbTaSe, which is believed to have a topologically nontrivial band structure…
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…
Raman study of lattice dynamics in Weyl semimetal TaAs
H. W. Liu, P. Richard, Z. D. Song +4
We report a polarized Raman study of Weyl semimetal TaAs. We observe all the optical phonons, with energies and symmetries consistent with our first-principles calculations. We det…
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…
