Terahertz frequency upconversion by coherently driving charge dynamics in the InSb/CdTe heterostructure
Pai Peng, Mingxiang Pan, Jiuming Liu +10
We investigate terahertz (THz) harmonic generation in the InSb/CdTe heterostructure, demonstrating, for the first time, efficient in-plane magnetic field-induced second-harmonic ge…

Magnetic order induced chiral phonons in a ferromagnetic Weyl semimetal
Mengqian Che, Jinxuan Liang, Yunpeng Cui +13
Chiral phonons are vibrational modes in a crystal that possess a well-defined handedness or chirality, typically found in materials that lack inversion symmetry. Here we report the…

Discovery of terahertz-frequency orbitally-coupled magnons in a kagome ferromagnet
Mengqian Che, Weizhao Chen, Maoyuan Wang +12
In ferromagnetic materials, magnons - quanta of spin waves - typically resonate in the gigahertz range. Beyond conventional magnons, while theoretical studies have predicted magnon…
