Symmetry-broken states in a system of interacting bosons on a two-leg ladder with a uniform Abelian gauge field
Symmetry-broken states in a system of interacting bosons on a two-leg ladder with a uniform Abelian gauge field
We study the quantum phases of bosons with repulsive contact interactions on a two-leg ladder in the presence of a uniform Abelian gauge field. The model realizes many interesting states, including Meissner phases, vortex-fluids, vortex-lattices, charge-density-waves and the biased-ladder phase. Our work focuses on the subset of these states that …
