Band-Insulator-Metal-Mott-Insulator transition in the half--filled $t - t^{'}$ ionic-Hubbard chain

G. I. Japaridze, R. Hayn, P. Lombardo +1

We investigate the ground state phase diagram of the half-filled $t - t^{'}$ repulsive Hubbard model in the presence of a staggered ionic potential $Δ$ , using the continuum-limi…

Nature of the metal-insulator transition in the half--filled t-t' Hubbard chain

G. I. Japaridze, R. M. Noack, D. Baeriswyl

We study the quantum phase transition from an insulator to a metal realized at t'=t'_c > 0.5t in the ground state of the half-filled Hubbard chain with both nearest-neighbor (t) an…
