Observation of Gapped Topological Surface States and Isolated Surface Resonances in PdTe Ultrathin Films
Jacob Cook, Sougata Mardanya, Qiangsheng Lu +7
The superconductor PdTe is known to host bulk Dirac bands and topological surface states. The coexistence of superconductivity and topological surface states makes PdTe a p…
Evidence of Magnon-Mediated Orbital Magnetism in a Quasi-2D Topological Magnon Insulator
Laith Alahmed, Xiaoqian Zhang, Jiajia Wen +13
We explore spin dynamics in Cu(1,3-bdc), a quasi-2D topological magnon insulator. The results show that the thermal evolution of Landé -factor () is anisotropic: $g_\textrm{i…
Observation of Unpinned Two-Dimensional Dirac States in Antimony Single Layers with Phosphorene Structure
Qiangsheng Lu, Matthew Snyder, Kyle Y. Chen +10
The discovery of graphene has stimulated enormous interest in two-dimensional (2D) electron gas with linear band structure. 2D Dirac materials possess many intriguing physical prop…
Giant Topological Hall Effect in van der Waals Heterostructures of CrTe2/Bi2Te3
Xiaoqian Zhang, Siddhesh C. Ambhire, Qiangsheng Lu +11
Discoveries of interfacial topological Hall effect (THE) provide an ideal platform for exploring physics arising from the interplay between topology and magnetism. The interfacial…
Dirac Fermion Cloning, Moir Flat Bands and Magic Lattice Constants in Epitaxial Monolayer Graphene
Qiangsheng Lu, Ching-Kai Chiu, Congcong Le +10
Tuning interactions between Dirac states in graphene has attracted enormous interest because it can modify the electronic spectrum of the two-dimensional material, enhance electron…
Electronic and magnetic properties of perovskite selenite and tellurite compounds: CoSeO, NiSeO, CoTeO and NiTeO
A. Rafi M. Iasir, Todd Lombardi, Qiangsheng Lu +4
Selenium and tellurium are among the few elements that form O perovskite structures with a four valent ion in the site. This leads to highly distorted structures and un…
Direct demonstration of the emergent magnetism resulting from the multivalence Mn in a LaMnO3 epitaxial thin film system
Wei Niu, Wenqing Liu, Min Gu +14
Atomically engineered oxide heterostructures provide a fertile ground for creating novel states. For example, a two-dimensional electron gas at the interface between two oxide insu…
