Parametric instabilities of interacting bosons in periodically-driven 1D optical lattices
K. Wintersperger, M. Bukov, J. Näger +6
Periodically-driven quantum systems are currently explored in view of realizing novel many-body phases of matter. This approach is particularly promising in gases of ultracold atom…
Matter-wave diffraction from a quasicrystalline optical lattice
Konrad Viebahn, Matteo Sbroscia, Edward Carter +2
Quasicrystals are long-range ordered and yet non-periodic. This interplay results in a wealth of intriguing physical phenomena, such as the inheritance of topological properties fr…
Non-Equilibrium Mass Transport in the 1D Fermi-Hubbard Model
S. Scherg, T. Kohlert, J. Herbrych +6
We experimentally and numerically investigate the sudden expansion of fermions in a homogeneous one-dimensional optical lattice. For initial states with an appreciable amount of do…
Non-power-law universality in one-dimensional quasicrystals
Attila Szabó, Ulrich Schneider
We have investigated scaling properties of the Aubry-André model and related one-dimensional quasiperiodic Hamiltonians near their localisation transitions. We find numerically tha…
