Visualizing band selective enhancement of quasiparticle lifetime in a metallic ferromagnet
Na Hyun Jo, Yun Wu, Thaís V. Trevisan +8
Electrons navigate more easily in a background of ordered magnetic moments than around randomly oriented ones. This fundamental quantum mechanical principle is due to their Bloch w…
Electronic structure of topological superconductor candidate AuPb
Yun Wu, Gil Drachuck, Lin-Lin Wang +8
We use magnetization measurements, high-resolution angle-resolved photoemission spectroscopy (ARPES), and density functional theory (DFT) calculations to study the electronic prope…
Extremely large magnetoresistance and Kohler's rule in PdSn4: a complete study of thermodynamic, transport and band structure properties
Na Hyun Jo, Yun Wu, Lin-Lin Wang +8
The recently discovered material PtSn is known to exhibit extremely large magnetoresistance (XMR) that also manifests Dirac arc nodes on the surface. PdSn is isostructure t…
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…
Discovery of unconventional charge density wave at the surface of K0.9Mo6O17
Daixiang Mou, Aashish Sapkota, H. -H. Kung +8
We use Angle Resolved Photoemission Spectroscopy (ARPES), Raman spectroscopy, Low Energy Electron Diffraction (LEED) and x-ray scattering to reveal an unusual electronically mediat…
Temperature induced Lifshitz transition in WTe2
Yun Wu, Na Hyun Jo, Masayuki Ochi +7
We use ultra-high resolution, tunable, VUV laser-based, angle-resolved photoemission spectroscopy (ARPES) and temperature and field dependent resistivity and thermoelectric power (…
