Mott transition in one dimension: Benchmarking dynamical cluster approaches
Matthias Balzer, Werner Hanke, Michael Potthoff
The variational cluster approach (VCA) is applied to the one-dimensional Hubbard model at zero temperature using clusters (chains) of up to ten sites with full diagonalization and…

Phase separation and competition of superconductivity and magnetism in the two-dimensional Hubbard model: From strong to weak coupling
M. Aichhorn, E. Arrigoni, M. Potthoff +1
Cooperation and competition between the antiferromagnetic, d-wave superconducting and Mott-insulating states are explored for the two-dimensional Hubbard model including nearest an…
