Correlated Topological Phases and Exotic Magnetism with Ultracold Fermions
Peter P. Orth, Daniel Cocks, Stephan Rachel +3
Motivated by the recent progress in engineering artificial non-Abelian gauge fields for ultracold fermions in optical lattices, we investigate the time-reversal-invariant Hofstadte…
Time-Reversal-Invariant Hofstadter-Hubbard Model with Ultracold Fermions
Daniel Cocks, Peter P. Orth, Stephan Rachel +3
We consider the time-reversal-invariant Hofstadter-Hubbard model which can be realized in cold atom experiments. In these experiments, an additional staggered potential and an arti…
Effects of Smooth Boundaries on Topological Edge Modes in Optical Lattices
Michael Buchhold, Daniel Cocks, Walter Hofstetter
Since the experimental realization of synthetic gauge fields for neutral atoms, the simulation of topologically non-trivial phases of matter with ultracold atoms has become a major…
