(a) Oscillating conductance as a function of magnetic flux in unit of h/e at variable temperatures. (b,c) Schematic diagram of the Weyl nodes projected onto the two-dimensional kxkz surface plane (b) without and (c) with an external magnetic field. The right-handed chirality and left-handed chirality are denoted by the red ball and blue ball, respectively. The Fermi arcs connect the Weyl nodes with opposite chirality. Without magnetic field, each Dirac node consists of two degenerate Weyl nodes. A magnetic field can separate the two degenerate Weyl nodes in the momentum space.
