Mixing-demixing transition in one-dimensional boson-fermion mixtures

Abstract

Mixing-demixing transitions in one-dimensional mixtures of fermions and bosons are numerically investigated. With Monte Carlo simulations, we searched the transitions by changing various parameters such as number densities of each component, fermion-boson interactions, boson-boson interactions, and hopping energies. In most cases we found clear evidences of the mixing-demixing transitions. We also identified the roles of each microscopic parameter in the transitions.
