Leveraging Chirality for Extreme Control of Light

In this talk, I will discuss our recent progress in tailored broken geometrical symmetries to control the interaction of light with structured materials and metasurfaces. In particular, I will discuss our theoretical and experimental work on nonlocal metasurfaces supporting chiral eigenstates, locally structured with subwavelength resolution. I will also discuss the unique opportunities that chirality and rotational broken symmetry enables in the context of polaritonic systems and time metamaterials.
