Surface plasmons can be Poincaré engineered to dress proximate materials via Floquet mechanism and encode quantum information on the nano-femto scales.
The NanoFemto Dynamics group is directed by Dr. Yanan Dai in the department of physics, Southern University of Science and Technology. Our research aims to understand how structured light and polariton fields interact with low dimensional materials, and how they can engineer exotic nonequilibrium quantum phases of matter. i.e. Poinacré engineering, on the nanometer and femtosecond (nanofemto) spatiotemporal scales. To probe the nanofemto dynamics of excited quantum mater, we develop laser-based ultrafast (phase-resolved) optical, and photoemission electron spectromicroscopy techniques that allow <10 nm spatial resolution and ~100 attosecond temporal accuracy.
