Shedding nano-light on quantum materials

I will present our recent work on nano-spectroscopy and nano-imaging of van der Waals (vdW) materials and interfaces. I am particularly excited with two recent results:

1) Good plasmons in a bad metal: MoOCl2 is the latest addition to hyperbolic vdW materials with
non-trivial electrodynamics spanning a broad range of frequencies from mid-IR to visible / Frank Ruta et al. Science 387, 786 (2025);

2) vdW waveguide quantum electrodynamics: we observed notable Purcell enhancement of the spontaneous emission produced by MoTe2 monolayers integrated in WSe2 waveguides /Sam Moore et al. Nature Photonics 2025/.
