Ferromagnetism in the Hubbard Model on the Infinite Dimensional fcc Lattice
Martin Ulmke
The Hubbard model on the fcc lattice is studied in the limit of infinite spatial dimensions. At sufficiently strong interaction finite temperature Quantum Monte Carlo calculations…

Anderson-Hubbard Model in
M. Ulmke, V. Janis, D. Vollhardt
We present a detailed, quantitative study of the competition between interaction- and disorder-induced effects in electronic systems. For this the Anderson-Hubbard model with diago…
