Luttinger Liquid of Polarons in One-Dimensional Boson-Fermion Mixtures
Luttinger Liquid of Polarons in One-Dimensional Boson-Fermion Mixtures
We use bosonization approach to investigate quantum phases in mixtures of bosonic and fermionic atoms confined in one dimensional optical lattices. The phase diagrams can be well understood in terms of polarons, which correspond to atoms that are "dressed" by screening clouds of the other atom species. For a mixture …
