Chiral phonons in a square lattice
Qianqian Wang, Si Li, Jiaojiao Zhu +5
Chiral phonons were initially proposed and further verified experimentally in two-dimensional (2D) hexagonal crystal lattices. Many intriguing features brought about by chiral phon…

Gate-tunable chiral phonons in low-buckled group-IVA monolayers
Hanyu Wang, Zhichao Zhou, Hao Chen +3
We investigate the electric response of chiral phonons on the low-buckled group-IVA monolayers by performing first-principles calculations. The vertical electric field breaks the d…
