WebHere, we report a non-adiabatic topological pumping that can adiabatically manipulate anomalous Floquet topological states in a 1D periodically-driven systems. We propose and demonstrate in waveguide array simulations Thouless-like topological pumping of non-adiabatic topological systems. WebJul 8, 2015 · A gas of electrons in a one-dimensional periodic potential can be transported even in the absence of a voltage bias if the potential is modulated slowly and periodically …
WebAbstract. We experimentally demonstrate topologically protected transport in the presence of disorder for a Thouless pump in a photonic waveguide lattice. This concept may lead to robust high density optical interconnects and slow light devices. View More...
WebJun 2, 2024 · The Thouless pump is a phenomenon in which $\\mathrm{U}(1)$ charges are pumped from an edge of a fermionic system to another edge. The Thouless pump has been generalized in various dimensions and for various charges.
