@article{Bauer2007FielddependentQI, title={Field-dependent quasiparticles in the infinite-dimensional Hubbard model}, author={Johannes Bauer and A. C. Hewson}, journal={Physical Review B}, year={2007}, volume={76}, pages={035118} }

We present dynamical mean-field theory (DMFT) results for the local spectral densities of the one- and two-particle response functions for the infinite-dimensional Hubbard model in a magnetic field. We look at the different regimes corresponding to half-filling, near half-filling, and well away from half-filling, for intermediate and strong values of the local interaction $U$. The low energy results are analyzed in terms of quasiparticles with field-dependent parameters. These renormalized…
