摘要
First-principles calculations have recently been used to develop comprehensive databases of nonmagnetic topological materials that are protected by time-reversal or crystalline symmetry.However,owing to the low symmetry requirement of Weyl points,a symmetry-based approach to identifying topological states cannot be applied to Weyl semimetals(WSMs).To date,WSMs with Weyl points in arbitrary positions are absent from the well-known databases.
