Scaling theory of the Mott-Hubbard metal-insulator transition in one dimension

C. A. Stafford, A. J. Millis

We use the Bethe ansatz equations to calculate the charge stiffness $D_{\mathrm{c}}=(L/2)d^2{E}_0/d{\Phi }_{\mathrm{c}}^2{|}_{{\Phi }_{\mathrm{c}}=0}$ of the one-dimensional repulsive-interaction Hubbard mod…
