http://cjqs.tju.edu.cn/info/1138/3333.htm WebHere we report the direct observation of two new plasmon modes in macroscopic tBLG with a highly ordered moiré superlattice. Using spiral structured nanoribbons of tBLG, we identify signatures of chiral plasmons that arise owing to the uncompensated Berry flux of the electron gas under optical pumping.

WebA quantum hydrodynamic model is used to study the edge modes of chiral Berry plasmons. The tran- scendental equation of the dispersion relation is solved nonlinearly and semi-analytically. We predict a new one-way chiral edge state with the quantum effect compared to that without the quantum effect, at the both side of q = 0. raymond linkedinWebAug 11, 2024 · Because of the quantum coupling between the twisted atomic layers, light-matter interaction is inherently chiral; as such, they provide a promising platform for chiral plasmons in the extreme nanoscale. However, while the interlayer quantum coupling can be significant, its influence on chiral plasmons still remains elusive. raymond li paul hastings houseWebJul 5, 2024 · Chiral Berry plasmons propagate along the edges of a two-dimensional metal surface with a finite Berry flux.
