In close collaboration of theory and experiment, we investigate how in Rice-Mele models with non-adiabatic, time-periodic drive the Floquet band structure can be engineered for topologically quantized transport, using dissipation or interaction. Experimentally, these systems are realized by plasmonic waveguide arrays which mathematically resemble a dissipative Schrödinger equation, the propagation axis playing the role of time. For the theoretical analysis of the experiments we develop a Floquet-Lindblad formalism for lossy systems and the Keldysh-Floquet formalism for interacting topological systems.
