Superconducting ground state of the two-dimensional Hubbard model: a variational study
David Eichenberger, Dionys Baeriswyl
A trial wave function is proposed for studying the instability of the two-dimensional Hubbard model with respect to d-wave superconductivity. Double occupancy is reduced in a simil…

Nature of the metal-insulator transition in the half--filled t-t' Hubbard chain
G. I. Japaridze, R. M. Noack, D. Baeriswyl
We study the quantum phase transition from an insulator to a metal realized at t'=t'_c > 0.5t in the ground state of the half-filled Hubbard chain with both nearest-neighbor (t) an…
