Hidden phonon-assisted charge density wave transition in BaFe2Al9 revealed by ultrafast optical spectroscopy
Lei Wang, Mingwei Ma, Jiangxu Li +10
The interplay between electronic and lattice degrees of freedom is fundamental to charge density wave (CDW) formation, yet the microscopic origin often remains elusive. Here, we in…

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…
