Spin polarization and texture of the Fermi arcs in the Weyl Fermion semimetal TaAs

Su-Yang Xu, Ilya Belopolski, Daniel S. Sanchez +25

A Weyl semimetal is a new state of matter that host Weyl fermions as quasiparticle excitations. The Weyl fermions at zero energy correspond to points of bulk band degeneracy, Weyl…
