Variational ground states of the two-dimensional Hubbard model
D. Baeriswyl, D. Eichenberger, M. Menteshashvili
Recent refinements of analytical and numerical methods have improved our understanding of the ground-state phase diagram of the two-dimensional (2D) Hubbard model. Here we focus on…
Superconductivity in the 2D Hubbard model: Electron doping is different
D. Eichenberger, D. Baeriswyl
A variational Monte Carlo calculation is used for studying the ground state of the two-dimensional Hubbard model, including hopping between both nearest and next-nearest neighbor s…
Superconductivity and antiferromagnetism in the two-dimensional Hubbard model: a variational study
D. Eichenberger, D. Baeriswyl
A variational ground state of the repulsive Hubbard model on a square lattice is investigated numerically for an intermediate coupling strength (U = 8t) and for moderate sizes (fro…
Superconductivity in the two-dimensional Hubbard model?
D. Baeriswyl, D. Eichenberger, B. Gut
A refined variational wave function for the two-dimensional repulsive Hubbard model is studied numerically, with the aim of approaching the difficult crossover regime of intermedia…
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…
