Surface Fermi arc connectivity in the type-II Weyl semimetal candidate WTe${}_2$

J. Sánchez-Barriga, M. G. Vergniory, D. Evtushinsky +4

We perform ultrahigh resolution angle-resolved photoemission experiments at a temperature T=0.8 K on the type-II Weyl semimetal candidate WTe${}_2$. We find a surface Fermi arc con…
