Frustrated magnets without geometrical frustration in bosonic flux ladders

We propose a scheme to realize a frustrated Bose-Hubbard model with ultracold atoms in an optical lattice that comprises the frustrated spin-1/2 quantum XX model. Our approach is based on a square ladder of magnetic flux ∼π with one real and one synthetic spin dimension. Although this system does no...
