Interactions enable Thouless pumping in a nonsliding lattice
Konrad Viebahn, Anne-Sophie Walter, Eric Bertok +5
A topological 'Thouless' pump represents the quantised motion of particles in response to a slow, cyclic modulation of external control parameters. The Thouless pump, like the quan…
Topological Floquet engineering using two frequencies in two dimensions
Yixiao Wang, Anne-Sophie Walter, Gregor Jotzu +1
Using two-frequency driving in two dimensions opens up new possibilites for Floquet engineering, which range from controlling specific symmetries to tuning the properties of resona…
Reversal of quantised Hall drifts at non-interacting and interacting topological boundaries
Zijie Zhu, Marius Gächter, Anne-Sophie Walter +2
The transport properties of gapless edge modes at boundaries between topologically distinct domains are of fundamental and technological importance. Therefore, it is crucial to gai…
