Abstract

The ground state properties of the one-dimensional fermionic Hubbard model in traps with an underlying lattice were investigated using quantum Monte Carlo (QMC) simulations. It was observed that due to the confining potential the density was space dependent, and Mott-insulating domains always coexist with metallic regions. A local compressibility was defined which characterized the Mott-insulating regions and analyzed other local quantities. A generic form for the phase diagram was developed which allows to compare systems with different values of all the parameter involved in the model.
