Imaging emergent exotic quasiparticle state in a frustrated transition metal oxide
Yuita Fujisawa, Anjana Krishnadas, Chia-Hsiu Hsu +10
The existence of rich Fermiology in anomalous metal phase in exotic superconductors has attracted considerable interests, as exemplified in copper, iron-based, and intermetallic fr…
Anomalous vortex shape in a frustrated superconductor hosting chiral multicomponent order parameters
Yuita Fujisawa, Anjana Krishnadas, Tomonori Nakamura +12
Multicomponent chiral superconductors can host spatially separated superconducting components within a single Abrikosov vortex, leading to unconventional, anisotropic vortex shapes…
Intertwining of magnetism and charge ordering in kagome FeGe
Sen Shao, Jia-Xin Yin, Ilya Belopolski +11
Recent experiments report a charge density wave (CDW) in the antiferromagnet FeGe, but the nature of the charge ordering and the associated structural distortion remains elusive. W…
Widely Tunable Berry curvature in the Magnetic Semimetal Cr1+dTe2
Y. Fujisawa, M. Pardo-Almanza, C. H. Hsu +8
Magnetic semimetals have increasingly emerged as lucrative platforms hosting spin-based topological phenomena in real and momentum spaces. Of particular interest is the emergence o…
Proximity-Effect-Induced Anisotropic Superconductivity in Monolayer Ni-Pb Binary Alloy
Yen-Hui Lin, Chia-Hsiu Hsu, Iksu Jang +7
Proximity effect facilitates the penetration of Cooper pairs that permits superconductivity in normal metal, offerring a promising approach to turn heterogeneous materials into sup…
Observation of near EF Fermi-arc van Hove singularity with prominent coupling to phonon in a van der Waals coupled Weyl semimetal
Z. Wang, Cheng-Yi Huang, Chia-Hsiu Hsu +7
A van der Waals coupled Weyl semimetal material NbIrTe4 is investigated by combining scanning tunneling microscopy/spectroscopy and first principles calculations. We observe a shar…
Co-existence of Topological Non-trivial and Spin Gapless Semiconducting Behavior in MnPO: A Composite Quantum Compound
Chia-Hsiu Hsu, P. C. Sreeparvathy, Chanchal K. Barman +2
Composite quantum compounds (CQC) are classic example of quantum materials which host more than one apparently distinct quantum phenomenon in physics. Magnetism, topological superc…
Itinerant ferromagnetism mediated by giant spin polarization of metallic ligand band in van der Waals magnet Fe5GeTe2
K. Yamagami, Y. Fujisawa, B. Driesen +15
We investigate near-Fermi-energy (EF) element-specific electronic and spin states of ferromagnetic van der Waals (vdW) metal Fe5GeTe2. The soft x-ray angle-resolved photoemission s…
Quantum Well Electronic States in Spatially Decoupled 2D Pb Nanoislands on Nb-doped SrTiO3(001)
Guan-Yu Chen, Chia-Hsiu Hsu, Bo-You Liu +4
Two-dimensional (2D) Pb nanoisland has established an ideal platform for studying the quantum size effects on growth mechanism, electronic structures as well as high-temperature su…
Topological surface electronic states in candidate nodal-line semimetal CaAgAs
Xiao-Bo Wang, Xiao-Ming Ma, Eve Emmanouilidou +10
We investigate systematically the bulk and surface electronic structure of the candidate nodal-line semimetal CaAgAs by angle resolved photoemission spectroscopy and density functi…
Direct Evidence of Interaction-Induced Dirac Cones in Monolayer Silicene/Ag(111) System
Ya Feng, Defa Liu, Baojie Feng +21
Silicene, analogous to graphene, is a one-atom-thick two-dimensional crystal of silicon which is expected to share many of the remarkable properties of graphene. The buckled honeyc…
