arXiv:1901.08234 Title: A Single Pair of Weyl Fermions in Half-metallic EuCd2As2 Semimetal Authors: Lin-Lin Wang, Na Hyun Jo, Brinda Kuthanazhi, Yun Wu, Robert J. McQueeney, Adam Kaminski and Paul C. Canfield llw@ameslab.gov Band structures in Fig.1, 3 and 5 have been calculated in VASP.5.2.12 with PBE+U+SOC and other settings for different magnetic configurations. Crystal structure in Fig.1b has been plotted in Vesta-3.4.0. Berrycurvature in Fig.1f and Fermi arcs in Fig.2 have been calculated in WannierTools-2.0 using tight-binding model constructed with maximally localized Wannier functions in Wannier90-2.1.0. Band structures in Fig.4 have been plotted for the 4-band low-energy Hamiltionian with parameters listed in the main text.
