Dynamical mean-field study of the Mott transition in thin films
M. Potthoff, W. Nolting
The correlation-driven transition from a paramagnetic metal to a paramagnetic Mott-Hubbard insulator is studied within the half-filled Hubbard model for a thin-film geometry. We co…

The moment sum rule and its consequences for ferromagnetism in the Hubbard model
M. Potthoff, T. Herrmann, T. Wegner +1
The sum rule for the moments of the spectral density is discussed for the single-band Hubbard model. It is shown that respecting the sum rule up to the order m=3 is conceptually im…
