Giant-exchange-driven Vectorial Control of a Minimal Topological Magnet in Eu3In2As4
Haonan Chen, Xunkai Duan, Guangyi Wang +13
The interplay between magnetism and band topology provides a route to controlling quantum states of matter, yet its realization in materials is often constrained by weak exchange c…
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…
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…
