The non-Abelsolis photon pump was designed and fabricated on photonic chip, providing a new tool for observing non-Abelian topological physics and a new technical route for topological manipulation of photon states and their paths using Wilczek-Zee and Le transform on chip. The research results were published online as a long article in Nature Physics under the title "Non-Abelian Thouless pumping in photonic waveguides."
