  The family of binary compounds including TaAs, TaP, NbAs, and NbP was
recently discovered as the first realization of Weyl semimetals. In order to
develop a comprehensive description of the charge carriers in these Weyl
semimetals, we performed systematic electronic structure calculations which
reveal the nature of Fermi surfaces and their complex interconnectivity in
TaAs, TaP, NbAs, and NbP. Our work report the first comparative and
comprehensive study of Fermi surface topology and band structure details of all
known members of the Weyl semimetal family and provide the necessary building
blocks for advancing our understanding of their unique topologically protected
low-energy Weyl fermion physics.
