In-Situ Polarimetry in Collimated Magneto-Infrared Spectroscopy System
Zeping Shi, Wenbin Wu, Zhiwei Zhang +14
Magneto-infrared spectroscopy under strong magnetic fields provides a powerful probe of Landau quantization and field-induced collective excitations, yet its full potential has lon…
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…
