Chargedensitywave phases of the generalized tV model
Abstract
The onedimensional extended tV model of fermions on a lattice is a model with repulsive interactions of finite range that exhibits a transition between a Luttinger liquid conducting phase and a Mott insulating phase. It is known that by tailoring the potential energy of the insulating system, one can force a phase transition into another insulating phase. We show how to construct all possible chargedensitywave phases of the system at low critical densities in the atomic limit. Higher critical densities are investigated by a bruteforce analysis of the possible finite unit cells of the Fock states.
