Atomic correlations in itinerant ferromagnets: quasi-particle bands of nickel
J. Buenemann, F. Gebhard, T. Ohm +11
We measure the band structure of nickel along various high-symmetry lines of the bulk Brillouin zone with angle-resolved photoelectron spectroscopy. The Gutzwiller theory for a nin…

Landau-Gutzwiller quasi-particles
J. Buenemann, F. Gebhard, R. Thul
We define Landau quasi-particles within the Gutzwiller variational theory, and derive their dispersion relation for general multi-band Hubbard models in the limit of large spatial…
