Quantum coherent states of interacting Bose-Fermi mixtures in one dimension
We study two-component atomic gas mixtures in one dimension involving both bosons and fermions. When the interspecies interaction is attractive, we report a rich variety of coherent ground-state phases that vary with the intrinsic and relative strength of the interactions. We avoid any artifacts of...

| description | We study two-component atomic gas mixtures in one dimension involving both bosons and fermions. When the interspecies interaction is attractive, we report a rich variety of coherent ground-state phases that vary with the intrinsic and relative strength of the interactions. We avoid any artifacts of lattice discretization by developing an implementation of a continuous matrix-product-state Ansatz for mixtures and priorly demonstrate the validity of our approach on the integrable point that exists for mixtures with equal masses and interactions (Lai-Yang model), where we find that the Ansatz correctly and systematically converges towards the exact results. |
