Origin of Giant Phonon Magnetic Moment in Orbital Seebeck Effect: a Heisenberg-type L-L Coupling
Hong Sun, Jinxin Zhong, Yimin Yao +2
Inspired by the recent observation of the orbital Seebeck effect in alpha-quartz, we identify an intrinsic amplification mechanism for thermally generated phonon angular momentum a…

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…
