Quantum phase transition from a superfluid to a Mott insulator in a gas of ultracold atoms
Markus Greiner, Olaf Mandel, Tilman Esslinger +2
For a system at a temperature of absolute zero, all thermal fluctuations are frozen out, while quantum fluctuations prevail. These microscopic quantum fluctuations can induce a mac…

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…
