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…

Quantisation and its breakdown in a Hubbard-Thouless pump

Anne-Sophie Walter, Zijie Zhu, Marius Gächter +5

Geometric properties of waves and wave functions can explain the appearance of integer-valued observables throughout physics. For example, these 'topological' invariants describe t…

Suppressing dissipation in a Floquet-Hubbard system

Konrad Viebahn, Joaquìn Minguzzi, Kilian Sandholzer +3

The concept of `Floquet engineering' relies on an external periodic drive to realise novel, effectively static Hamiltonians. This technique is being explored in experimental platfo…
