The Mott-Anderson transition in the disordered one-dimensional Hubbard model

Show other versions (1)

We use the density matrix renormalization group to study the quantum transitions that occur in the half-filled one-dimensional fermionic Hubbard model with onsite potential disorder. We find a transition from the gapped Mott phase with algebraic spin correlations to a gapless spin-disordered phase b...
