A minimal, "hydrogen atom" version of an inversion-breaking Weyl semimetal
Ilya Belopolski, Peng Yu, Daniel S. Sanchez +15
The recent explosion of research interest in Weyl semimetals has led to many proposed Weyl semimetal candidates and a few experimental observations of a Weyl semimetal in real mate…
Anisotropic physical properties and pressure dependent magnetic ordering of CrAuTe
Na Hyun Jo, Udhara S. Kaluarachchi, Yun Wu +6
Systematic measurements of temperature dependent magnetization, resistivity and angle-resolved photoemission spectroscopy (ARPES) at ambient pressure as well as resistivity under p…
Enhancement of the superconducting gap by nesting in CaKFe4As4 - a new high temperature superconductor
Daixiang Mou, Tai Kong, William R. Meier +9
We use high resolution angle resolved photoemission spectroscopy and density functional theory with experimentally obtained crystal structure parameters to study the electronic pro…
Measuring Chern numbers above the Fermi level in the Type II Weyl semimetal MoWTe
Ilya Belopolski, Su-Yang Xu, Yukiaki Ishida +30
It has recently been proposed that electronic band structures in crystals give rise to a previously overlooked type of Weyl fermion, which violates Lorentz invariance and, conseque…
Observation of Fermi Arcs in Type-II Weyl Semimetal Candidate WTe2
Yun Wu, Na Hyun Jo, Daixiang Mou +4
We use ultrahigh resolution, tunable, vacuum ultraviolet laser angle-resolved photoemission spectroscopy (ARPES) to study the electronic properties of WTe, a material that was…
Asymmetric mass acquisition in LaBi - a new topological semimetal candidate
Yun Wu, Tai Kong, Lin-Lin Wang +7
We use our high resolution He-lamp based, tunable laser-based ARPES measurements and density functional theory calculations to study the electronic properties of LaBi, a binary sys…
