Topological charge pumping in the interacting bosonic Rice-Mele model
A. L. C. Hayward, C. Schweizer, M. Lohse +2
We investigate topological charge pumping in a system of interacting bosons in the tight-binding limit, described by the Rice-Mele model. An appropriate topological invariant for t…

Coupling ultracold matter to dynamical gauge fields in optical lattices: From flux-attachment to Z2 lattice gauge theories
Luca Barbiero, Christian Schweizer, Monika Aidelsburger +3
Artificial magnetic fields and spin-orbit couplings have been recently generated in ultracold gases in view of realizing topological states of matter and frustrated magnetism in a…
