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…
A dynamical stability limit for the charge density wave in K0.3MoO3
Roman Mankowsky, Biaolong Liu, Srivats Rajasekaran +6
We study the response of the one-dimensional charge density wave in K0.3MoO3 to different types of excitation with femtosecond optical pulses. We compare the response to direct exc…
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 (…
Anomalous High-Energy Waterfall-Like Electronic Structure in 5d Transition Metal Oxide Sr2IrO4 with a Strong Spin-Orbit Coupling
Yan Liu, Li Yu, Xiaowen Jia +21
The layered 5d transition metal oxides like Sr2IrO4 have attracted significant interest recently due to a number of exotic and new phenomena induced by the interplay between the sp…
