Observation of Flat Bands in Type-II Weyl Semimetal TaRhTe
Harry Rankin, Tyler J. Slade, Benjamin Schrunk +7
Flat bands have been theoretically predicted for decades but have only recently been realized in quantum materials such as magic-angle twisted bilayer graphene, kagome and Lieb lat…
Robust two-dimensional surface superconductivity and vortex lattice in the Weyl semimetal -PtBi
Jose Antonio Moreno, Pablo García Talavera, Pablo GarcÃa Talavera +11
The layered compound -PtBi is a topological semimetal with Fermi arcs at the surface joining bulk Weyl points. Recent work has found signatures of surface superconductivity…
Intrinsic Layer-Dependent Surface Energy and Exfoliation Energy of van der Waals Materials
Lin-Lin Wang, Jiaqiang Yan, Yong Han +6
Stacking and twisting 2D van der Waals (vdW) layers have become versatile platforms to tune electron correlation. These platforms rely on exfoliating vdW materials down to a single…
Observation of unexpected band splitting and magnetically-induced band structure reconstruction in TbTiBi
Yevhen Kushnirenko, Lin-Lin Wang, Xiaoyi Su +5
The magnetic Kagome materials are a promising platform to study the interplay between magnetism, topology, and correlated electronic phenomena. Among these materials, the RTi3Bi4 f…
Topography of Fermi Arcs in t-PtBi Using High Resolution Angle-resolved Photoemission Spectroscopy
Evan O'Leary, Zhuoqi Li, Lin-Lin Wang +4
We use high resolution angle-resolved photoemission spectroscopy (ARPES) and density functional theory (DFT) to investigate the electronic structure of trigonal phase ${\rm PtBi_2}…
Design and Predict Tetragonal van der Waals Layered Quantum Materials of MPdI (M=Ga, In and 3 Transition Metals)
Niraj K. Nepal, Tyler J. Slade, Joanna M. Blawat +8
Quantum materials with stacked van der Waals (vdW) layers hosting non-trivial band structure topology and magnetism have shown many interesting properties. Using high throughput de…
