Abstract

Many emerging technologies in adaptive optics, energy conversion, and storage demand powerful design tools for nanophotonics. Phase, symmetry, and topology arising from quantum many-body effects are such powerful tools that bring a paradigm shift to nanophotonics. Here, we present two classes of nanophotonic devices based on quantum many-body systems. In the first case, non-Hermitian nanophotonic devices with non-trivial topology enable efficient solid-state energy conversion and thermal imaging. In the latter, light-matter interaction in a quantum material enables ultra-low power nonlinear optical devices. These approaches demonstrate how the new powerful design tools break many inherent trade-offs and pave the way for extreme nanophotonics.
