Protected quantum gates using qubit doublons in dynamical optical lattices
Yann Kiefer, Zijie Zhu, Lars Fischer +5
Quantum computing represents a central challenge in modern science. Neutral atoms in optical lattices have emerged as a leading computing platform, with collisional gates offering…
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…
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…
