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…

Low Temperature Lanczos Method
Markus Aichhorn, Maria Daghofer, Hans Gerd Evertz +1
We present a modified finite temperature Lanczos method for the evaluation of dynamical and static quantities of strongly correlated electron systems that complements the finite te…
