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…

Spectral density of the Hubbard-model by the continued fraction method

R. Hayn, P. Lombardo, K. Matho

We present the continued fraction method (CFM) as a new microscopic approximation to the spectral density of the Hubbard model in the correlated metal phase away from half filling.…
