Discovery of a Weyl Fermion Semimetal and Topological Fermi Arcs
Su-Yang Xu,Ilya Belopolski,Nasser Alidoust,Madhab Neupane,Chenglong Zhang,Raman Sankar,Shin-Ming Huang,Chi-Cheng Lee,Guoqing Chang,Baokai Wang,Guang Bian,Hao Zheng,Daniel S. Sanchez,Fangcheng Chou,Hsin Lin,Shuang Jia,M. Zahid Hasan +16 more
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.

Discovery of a Weyl fermion semimetal and topological Fermi arcs
Su-Yang Xu,Ilya Belopolski,Nasser Alidoust,Madhab Neupane,Madhab Neupane,Guang Bian,Chenglong Zhang,Raman Sankar,Guoqing Chang,Zhujun Yuan,Chi-Cheng Lee,Shin-Ming Huang,Hao Zheng,Jie Ma,Daniel S. Sanchez,Baokai Wang,Baokai Wang,Arun Bansil,Fangcheng Chou,Pavel Shibayev,Hsin Lin,Shuang Jia,M. Zahid Hasan +22 more
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
Shin-Ming Huang,Su-Yang Xu,Ilya Belopolski,Chi-Cheng Lee,Guoqing Chang,Baokai Wang,Baokai Wang,Nasser Alidoust,Guang Bian,Madhab Neupane,Madhab Neupane,Chenglong Zhang,Shuang Jia,Arun Bansil,Hsin Lin,M. Zahid Hasan +15 more
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
