Effect of disorder on topological charge pumping in the Rice-Mele model
A. L. C. Hayward, E. Bertok, U. Schneider +1
Recent experiments with ultracold quantum gases have successfully realized integer-quantized topological charge pumping in optical lattices. Motivated by this progress, we study th…
Topological phases in the Fermi-Hofstadter-Hubbard model on hybrid-space ladders
Leo Stenzel, Andrew L. C. Hayward, Ulrich Schollwöck +1
In recent experiments with ultracold atoms, both two-dimensional (2d) Chern insulators and one-dimensional (1d) topological charge pumps have been realized. Without interactions, b…
Quantum phases and topological properties of interacting fermions in one-dimensional superlattices
Leo Stenzel, Andrew L. C. Hayward, Claudius Hubig +2
The realization of artificial gauge fields in ultracold atomic gases has opened up a path towards experimental studies of topological insulators and, as an ultimate goal, topologic…
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…
Pfaffian States in Coupled Atom-Cavity Systems
Andrew L. C. Hayward, Andrew M. Martin
Coupled atom-cavity arrays, such as those described by the Jaynes-Cummings Hubbard model, have the potential to emulate a wide range of condensed matter phenomena. In particular, t…
Superfluid-Mott transitions and vortices in the Jaynes-Cummings-Hubbard lattices with time reversal symmetry breaking
Andrew L. C. Hayward, Andrew M. Martin
We investigate the groundstate behaviour of Jaynes-Cummings-Hubbard lattices in the presence of a synthetic magnetic field, via a Gutzwiller ansatz. Specifically, we study the Mott…
