Electronic non-adiabatic states
Nikitas I. Gidopoulos, E. K. U. Gross
A novel treatment of non-adiabatic couplings is proposed. The derivation starts from the long-known, but not well-known, fact that the wave function of the complete system of elctr…

Born Effective Charge Reversal and Metallic Threshold State at a Band Insulator-Mott Insulator Transition
N. Gidopoulos S. Sorella, E. Tosatti
We study the quantum phase transition between a band (``ionic'') insulator and a Mott-Hubbard insulator, realized at a critical value U=Uc in a bipartite Hubbard model with two ine…
