Journal ArticleDOI

Discovery of a Weyl Fermion Semimetal and Topological Fermi Arcs

TL;DR: The experimental discovery of a Weyl semimetal, tantalum arsenide (TaAs), using photoemission spectroscopy, which finds that Fermi arcs terminate on the Weyl fermion nodes, consistent with their topological character.
Journal ArticleDOI

Discovery of a Weyl fermion semimetal and topological Fermi arcs

TL;DR: In this article, the experimental discovery of a Weyl semimetal, tantalum arsenide (TaAs), was reported, which is a new state of matter that hosts Weyl fermions as emergent quasiparticles and admits a topological classification that protects Fermi arcs on the boundary of a bulk sample.
Journal ArticleDOI

A Weyl Fermion semimetal with surface Fermi arcs in the transition metal monopnictide TaAs class

TL;DR: The results show that in the TaAs-type materials the WeylSemimetal 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.
Journal ArticleDOI

Theoretical Discovery/Prediction: Weyl Semimetal states in the TaAs material (TaAs, NbAs, NbP, TaP) class

TL;DR: In this article, the first Weyl semimetal was identified in a class of stoichiometric materials, including TaAs, TaP, NbAs, and NbP, which break crystalline inversion symmetry.
