DMFT vs Second Order Perturbation Theory for the Trapped 2D Hubbard-Antiferromagnet
Andreas D. Pfister, Eberhard Jakobi, Tobias Gottwald +1
In recent literature on trapped ultracold atomic gases, calculations for 2D-systems are often done within the Dynamical Mean Field Theory (DMFT) approximation. In this paper, we co…

FFLO- and Néel States in finite-size Systems
T. Gottwald, P. G. J. van Dongen
The general structure of the -wave fermionic superfluid pairing order parameter is discussed for systems in thermal equilibrium. We demonstrate that for finite-size systems with…
