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…
Chiral Phonons in Chiral Materials
Hao Chen, Weikang Wu, Jiaojiao Zhu +4
The concept of chirality makes ubiquitous appearance in nature. Particularly, both a structure and its collective excitations may acquire well defined chiralities. In this work, we…
Symmetry-Enforced Nodal Chain Phonons
Jiaojiao Zhu, Weikang Wu, Jianzhou Zhao +3
Topological phonons in crystalline materials have been attracting great interest. However, most cases studied so far are direct generalizations of the topological states from elect…
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…
