Mechanical resonances of mobile impurities in a one-dimensional quantum fluid
Thomas L. Schmidt, Giacomo Dolcetto, Christopher J. Pedder +2
We study a one-dimensional interacting quantum liquid hosting a pair of mobile impurities causing backscattering. We determine the effective retarded interaction between the two im…
Dimensional crossover and cold-atom realization of topological Mott insulators
Mathias S. Scheurer, Stephan Rachel, Peter P. Orth
We propose a cold-atom setup which allows for a dimensional crossover from a two-dimensional quantum spin Hall insulating phase to a three-dimensional strong topological insulator…
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…
Supersolidity of cold-atom Bose-Fermi mixtures in optical lattices
Peter P. Orth, Doron L. Bergman, Karyn Le Hur
We investigate a cold atomic mixture of spinless bosons and fermions in two-dimensional optical lattices. In the presence of a nested Fermi surface, the bosons may develop a fascin…
