Magnetic phases near the Van Hove singularity in s- and d-band Hubbard model
Marcus Fleck, Andrzej M. Oles, Lars Hedin
We investigate the magnetic instabilities of the nondegenerate (s-band) and a degenerate (d-band) Hubbard model in two dimensions using many-body effects due to the particle-partic…
Spectral and transport properties of doped Mott-Hubbard systems with incommensurate magnetic order
Marcus Fleck, Alexander I. Lichtenstein, Andrzej M. Oles +1
We present spectral and optical properties of the Hubbard model on a two-dimensional square lattice using a generalization of dynamical mean-field theory to magnetic states in fini…
Dynamical Mean-Field Theory for Doped Antiferromagnets
M. Fleck, A. I. Lichtenstein, A. M. Oles +2
We have generalized the dynamical mean-field theory to study the doping dependence of the crossover from antiferromagnetic to short-range order modelled by an incommensurate spin d…
