Three-dimensional topological insulator feature of ternary chalcogenide Ge2Bi2Te5
Shangjie Tian, Yuchong Zhang, Chenhao Liang +7
The exploration of novel topological insulators (TIs) beyond binary chalcogenides has been accelerated in pursuit of exotic quantum states and device applications. Here, the layere…
Magnetic-Field Control of Tomonaga-Luttinger Liquids in Ta2Pd3Te5 Edge States
Xingchen Guo Anqi Wang, Xiutong Deng, Yupeng Li +12
Ta2Pd3Te5 is a quasi-one-dimensional transition-metal telluride whose heavy atoms endow the material with strong spin-orbit coupling, while the Fermi level inside the bulk gap make…
Optical Excitations of Flat Bands Induced by Exciton Condensation in TaPdTe
Shaohui Yi, Zhiyu Liao, Chenhao Liang +10
We report on the charge dynamics of TaPdTe using temperature-dependent optical spectroscopy with polarized light. We observe a metal-insulator transition characterized…
Axion insulator, Weyl points, quantum anomalous Hall effect and magnetic topological phase transition in Eu3In2As4
Jingyu Yao, Ruihan Zhang, Sheng Zhang +5
The magnetic topological phases attract much interest, such as the axion insulator, higher-order topology, Weyl semimetals, and the quantum anomalous Hall effect (QAHE). Here, we p…
