Unoccupied electronic structure and signatures of topological Fermi arcs in the Weyl semimetal candidate MoWTe
Ilya Belopolski, Su-Yang Xu, Yukiaki Ishida +30
Weyl semimetals have sparked intense research interest, but experimental work has been limited to the TaAs family of compounds. Recently, a number of theoretical works have predict…
A strongly robust Weyl fermion semimetal state in TaS
Guoqing Chang, Su-Yang Xu, Daniel S. Sanchez +11
Weyl semimetals are extremely interesting. Although the first Weyl semimetal was recently discovered in TaAs, research progress is still significantly hindered due to the lack of r…
Atomic Scale Visualization of Quantum Interference on a Weyl Semimetal Surface by Scanning Tunneling Microscopy/Spectroscopy
Hao Zheng, Su-Yang Xu, Guang Bian +19
Weyl semimetals may open a new era in condensed matter physics, materials science and nanotech after graphene and topological insulators. We report the first atomic scale view of t…
Spin polarization and texture of the Fermi arcs in the Weyl Fermion semimetal TaAs
Su-Yang Xu, Ilya Belopolski, Daniel S. Sanchez +25
A Weyl semimetal is a new state of matter that host Weyl fermions as quasiparticle excitations. The Weyl fermions at zero energy correspond to points of bulk band degeneracy, Weyl…
Arc-tunable Weyl Fermion metallic state in MoWTe
Tay-Rong Chang, Su-Yang Xu, Guoqing Chang +13
Weyl semimetals may open a new era in condensed matter physics because they provide the first example of Weyl fermions, realize a new topological classification even though the sys…
Two distinct topological phases in the mixed valence compound YbB6 and its differences from SmB6
Tay-Rong Chang, Tanmoy Das, Peng-Jen Chen +6
We discuss the evolution of topological states and their orbital textures in the mixed valence compounds SmB6 and YbB6 within the framework of the generalized gradient approximatio…
