Variational cluster approach to spontaneous symmetry breaking: The itinerant antiferromagnet in two dimensions
C. Dahnken, M. Aichhorn, W. Hanke +2
Based on the self-energy-functional approach proposed recently [M. Potthoff, Eur. Phys. J. B 32, 429 (2003)], we present an extension of the cluster-perturbation theory to systems…

Quantum Monte Carlo and variational approaches to the Holstein model
Martin Hohenadler, Hans Gerd Evertz, Wolfgang von der Linden
Based on the canonical Lang-Firsov transformation of the Hamiltonian we develop a very efficient quantum Monte Carlo algorithm for the Holstein model with one electron. Separation…

Variational cluster approach to correlated electron systems in low dimensions
M. Potthoff, M. Aichhorn, C. Dahnken
A self-energy-functional approach is applied to construct cluster approximations for correlated lattice models. It turns out that the cluster-perturbation theory (Senechal et al, P…
