Phases of interacting bosons in a hybrid Harper-Hofstadter system with a synthetic dimension of harmonic trap states
David G. Reid, Holly A. J. Middleton-Spencer, Grazia Salerno +2
Synthetic dimensions are a powerful tool for engineering desired quantum systems, based on coupling together sets of states and reinterpreting these as lattice sites along an artif…
Topological Chiral Edge States in a Synthetic Dimension of Atomic Trap States
David G. Reid, Christopher Oliver, Patrick Regan +6
A key hallmark of quantum Hall physics is the existence of topological chiral states at the system boundary. Signatures of these edge states have been experimentally observed in co…
Drude weight and the many-body quantum metric in one-dimensional Bose systems
Grazia Salerno, Tomoki Ozawa, Päivi Törmä
We study the effect of quantum geometry on the many-body ground state of one-dimensional interacting bosonic systems. We find that the Drude weight is given by the sum of the kinet…
Supefluidity of flat band Bose-Einstein condensates revisited
Aleksi Julku, Grazia Salerno, Päivi Törmä
We consider the superfluid weight, speed of sound and excitation fraction of a flat band Bose-Einstein condensate (BEC) within multiband Bogoliubov theory. The superfluid weight is…
Bloch Oscillations Along a Synthetic Dimension of Atomic Trap States
Christopher Oliver, Aaron Smith, Thomas Easton +5
Synthetic dimensions provide a powerful approach for simulating condensed matter physics in cold atoms and photonics, whereby a set of discrete degrees of freedom are coupled toget…
Topological two-body bound states in the interacting Haldane model
Grazia Salerno, Marco Di Liberto, Chiara Menotti +1
We study the topological properties of the two-body bound states in an interacting Haldane model as a function of interparticle interactions. In particular, we identify topological…
How to directly observe Landau levels in driven-dissipative strained honeycomb lattices
Grazia Salerno, Tomoki Ozawa, Hannah M. Price +1
We study the driven-dissipative steady-state of a coherently-driven Bose field in a honeycomb lattice geometry. In the presence of a suitable spatial modulation of the hopping ampl…
