Coexistence of superconductivity and charge-density waves in a two-dimensional Holstein model at half-filling
S. Sykora, A. Hübsch, K. W. Becker
In one dimension the coupling of electrons to phonons leads to a transition from a metallic to a Peierls distorted insulated state if the coupling exceeds a critical value. On the…

Renormalization of the electron-phonon interaction: a reformulation of the BCS-gap equation
A. Huebsch, K. W. Becker
A recently developed renormalization approach is used to study the electron-phonon coupling in many-electron systems. By starting from an Hamiltonian which includes a small gauge s…
