First- and Second Order Phase Transitions in the Holstein-Hubbard Model
W. Koller, D. Meyer, Y. Ono +1
We investigate metal-insulator transitions in the Holstein-Hubbard model as a function of the on-site electron-electron interaction U and the electron-phonon coupling g. We use sev…

Magnetism and Superconductivity in a Two-band Hubbard Model in Infinite Dimensions
Y. Ono, K. Sano
We study a two-band Hubbard model using the dynamical mean-field theory combined with the exact diagonalization method. At the electron density , a transition from a band-insu…
