N2 - The ground state properties of the single-species noninteracting fermions confined on 1D optical lattices, were investigated. A system in which the center of the trap is initially displaced a small distance was studied, as well as the nonequilibrium dynamics of the fermionic cloud on a lattice. A detailed analysis of noninteracting systems focusing on the consequences of the combination of a combining and a periodic potential was performed. The results lead to a confinement of particles in a fraction of the available system size, which is directly related to the formation of insulating regions in the case of fermionic systems.
