A Weyl semimetal is an unusual crystal that hosts Weyl fermions as quasiparticle excitations and features Fermi arcs on its surface. Such a semimetal not only provides a condensed matter realization of the anomalies in quantum field theories but also demonstrates the topological classification beyond the gapped topological insulators. Here, we identify a topological Weyl semimetal state in the transition metal monopnictide materials class. Our first-principles calculations on TaAs reveal its bulk Weyl fermion cones and surface Fermi arcs. Our results show that in the TaAs-type materials the Weyl semimetal state does not depend on fine-tuning of chemical composition or magnetic order, which opens the door for the experimental realization of Weyl semimetals and Fermi arc surface states in real materials.","abstract_license":"CC-BY (publisher license, via OpenAlex)","license":"cc-by","is_open_access":true,"retracted":false,"peer_reviewed":null,"categories":["Topological Materials and Phenomena"],"details":null,"provenance":"openalex","attribution":"Abstract of \"A Weyl Fermion semimetal with surface Fermi arcs in the transition metal monopnictide TaAs class\" by Shin-Ming Huang, Su‐Yang Xu, Ilya Belopolski et al., https://doi.org/10.1038/ncomms8373, used under its Creative Commons Attribution license (CC-BY); markup removed, otherwise unmodified.","topics":[{"slug":"topological-matter","name":"Topological Phases & Anyons","domain_slug":"physics"}],"cited_in_dossiers":[{"slug":"topological-matter","title":"Topological Phases & Anyons: State of the Field (October 2026)","url":"https://space-kitty.com/dossiers/topological-matter"}]}
