Abstract

Bose-Fermi mixtures with attractive Bose-Fermi interactions in one-dimensional optical lattices are studied by using Quantum Monte Carlo simulations of an extended Bose-Fermi Hubbard model. We first derived the extended Hubbard model with the hopping terms of each species modified to include interaction effects. Bosonic Mott transition induced by introducing fermions into bosons is demonstrated by the simulations.
