Abstract

I will discuss how symmetry violations provide unique opportunities for nanophotonics, tailoring wave interactions in nanostructures for a wide range of functionalities. In particular, I will discuss broken geometrical symmetries for localized surface polaritons, the physics of moiré photonics, in-plane inversion symmetry breaking for valleytronics and nonradiative state control, time-reversal symmetry breaking for optical nonreciprocity, and parity-time symmetry breaking. Overall, this talk aims to present the role of low symmetry and broken symmetry in controlling nanoscale light and its widespread applications for optical technologies.
