## Description

- description: "We investigate the topological electronic properties of the \U0001D43E4
    crystal by constructing a tight-binding model. The bulk band structure hosts Weyl
    nodes with higher and conventional chiralities (\U0001D712=±2 and \U0001D712=±1)
    located at high-symmetry points in the Brillouin zone. Through analytical evaluation
    of the Berry curvature, we identify the positions and chiralities of these Weyl
    nodes. Furthermore, slab calculations for the (001) surface reveal Fermi arcs
    that connect Weyl nodes of opposite chirality, including those linking \U0001D712=±2
    nodes with pairs of \U0001D712=∓1 nodes. These results demonstrate that the \U0001D43E4
    crystal is a spinless Weyl semimetal featuring topologically protected surface
    states originating from multiple types of Weyl nodes."
