Giant Thermal-Conductivity Enhancement from Chiral-Phonon Pseudo-Angular Momentum Conservation
Tingting Wang, Dabao Zha, Hao Chen +2
Pseudo-angular momentum (PAM) underlies optical selection rules for chiral phonons, but whether it also constrains thermally populated finite-wave-number phonon-phonon scattering h…
Magic of nonlocal geometric force: lighting up optical transition and transporting angular momentum by chiral phonons
Hao Chen, Haoshu Li, Lifa Zhang +1
We investigate the impact of the nonlocal geometric force -- arising from the molecular Berry curvature -- on the lattice dynamics of magnetic materials with broken time-reversal s…
Ultrafast switching of photoinduced phonon chirality in the antiferrochiral BPO crystal
Hao Chen, Hanyu Wang, Tingting Wang +4
In crystalline systems, chiral crystals cannot interconvert to their enantiomorph post-synthesis without undergoing melting-recrystallization processes. However, recent work indica…
Phonon chirality manipulation mechanism in TMD interlayer-sliding ferroelectrics
Hao Chen, Qianqian Wang, Xukun Feng +2
As an ideal platform, both the theoretical prediction and first experimental verification of chiral phonons are based on transition-metal dichalcogenide materials. The manipulation…
Electrically Controllable Chiral Phonons in Ferroelectric Materials
Hao Chen, Weikang Wu, Kangtai Sun +2
Chiral phonons have attracted increasing attention, as they play important roles in many different systems and processes. However, a method to control phonon chirality by external…
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…
Chiral Phonon Activated Spin Seebeck Effect
Xiao Li, Jinxin Zhong, Jinluo Cheng +3
Efficient generation of spin polarization is the central focus of spintronics. In magnetic materials, spin currents can arise from heat currents by the conventional spin Seebeck ef…
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…
Valley Modulation and Single-Edge Transport of Magnons in Staggered Kagome Ferromagnets
Yuheng Xing, Hao Chen, Ning Xu +2
Owing to its charge-free property, magnon is highly promising to achieve dissipationless transport without Joule heating and thus potentially applicable to energy-efficient devices…
