Orbital-selective Mott transitions in a doped two-band Hubbard model with crystal field splitting
E. Jakobi, N. Blümer, P. G. J. van Dongen
We investigate the effects of crystal field splitting in a doped two-band Hubbard model with different bandwidths within dynamical mean-field theory (DMFT), using a quantum Monte C…

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…
