Finite-temperature investigation of quarter filled ladder systems
C. Gabriel, E. Sherman, T. C. Lang +2
We investigate charge ordering in a quarter-filled ladder at finite temperature by determinantal Quantum Monte Carlo. The sign problem is moderate in a wide range of model paramete…
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…
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…
