Anderson Localization versus Delocalization of Interacting Fermions in One Dimension
Anderson Localization versus Delocalization of Interacting Fermions in One Dimension
Using the density matrix renormalization group algorithm, we investigate the lattice model for spinless fermions in one dimension in the presence of a strong interaction and disorder. The phase sensitivity of the ground state energy is determined with high accuracy for systems up to a size of 60 lattice constants. …
