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…
Inelastic Neutron Scattering for Direct Detection of Chiral Phonons
Tingting Wang, Jun Zhou, Qingyong Ren +1
Chiral phonons have attracted significant attention due to their potential applications in spintronics, superconductivity, and advanced materials, but their detection has predomina…
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…
