In this work, we investigate the phonon scatterings in the light-matter strong coupling regime. The stimulated valley phonon scattering by the strong coupling regime is demonstrated in plasmonic cavities embedded with monolayer TMD.
In this work, we show that plasmon-enhanced optical trapping forces can overcome the thermal fluctuations of molecules, and demonstrate the optical trapping and release of single-molecules in the solutions.

In this paper, we theoretically investigate the Fano interference between molecular vibrations and plasmons, and unveil plasmon-mediated coherent intermolecular interactions.
In this work, we report the observation of giant lamb shift of single-molecule fluorescence that is coupled with a plasmonic cavity, which reveals the plasmon-molecule interactions at the single-molecule level.

In this work, we for the first time report the observation of intrinsic chiral phonons via transient infrared (IR) spectroscopy in the atomic lattice of monolayer WSe2. The broken inversion symmetry of the monolayer lattice lifts the degeneracy of clockwise and counterclockwise atomic rotations at the corners of the Brillouin zone.
In this review paper, we review the mechanism of plasmon-enhanced Raman scattering (PERS) and discussed PERS hotspots for surface characterization of various materials. In particular, a new generation of hotspots that are generated from hybrid structures combining PERS-active nanostructures and probe materials is highlighted.
