Quadratic light-matter interactions are nonlinear couplings such that quantum emitters interact with photonic or phononic modes exclusively via the exchange of excitation pairs. Implementable with atomic and solid-state systems. these couplings lead to a plethora of phenomena that have been characterized in the context of cavity QED. where quantum emitters interact with localized boso... https://foldlyers.shop/product-category/usb-3-1-type-c-gen-2-to-usb-type-c/
