Giant and Broadband Circular Dichroism from Particle-Hole Symmetry Breaking in Weyl Semimetals
Xiangyu Jiang, Zeping Shi, Yuhan Du +14
Circular dichroism originates from symmetry breaking of material structure, leading to differential absorption of left- and right-circularly polarized light. However, circular dich…
Defect Engineering for Stabilizing Magnetic and Topological Properties in Mn(Bi1-xSbx)2Te4
Haonan Chen, Jiayu Wang, Huayao Li +18
MnBi2Te4 is a versatile platform for exploring diverse topological quantum states, yet its potential is hampered by intrinsic antisite defects. While Sb substitution has been emplo…
A High-Flux and High-Efficiency Setup for Magneto-Infrared Spectroscopy
Zeping Shi, Wenbin Wu, Zhiwei Zhang +14
We report the design and implementation of a high-flux, high-efficiency magneto-infrared spectroscopy system optimized for broadband measurements in high magnetic fields. The setup…
Isotropic Dirac fermion and anomalous oscillator strength of zeroth Landau level transition
Zeping Shi, Wenbin Wu, Guangyi Wang +12
Dirac fermions, characterized by their linear dispersion and relativistic nature, have emerged as a prominent class of quasiparticles in condensed matter physics. While the Dirac e…
The discovery of three-dimensional Van Hove singularity
Wenbin Wu, Zeping Shi, Mykhaylo Ozerov +20
Arising from the extreme/saddle point in electronic bands, Van Hove singularity (VHS) manifests divergent density of states (DOS) and induces various new states of matter such as u…
