Field dependent quasiparticles in the infinite dimensional Hubbard model
J. Bauer, A. C. Hewson
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…
Renormalized quasiparticles in antiferromagnetic states of the Hubbard model
J. Bauer, A. C. Hewson
We analyze the properties of the quasiparticle excitations of metallic antiferromagnetic states in a strongly correlated electron system. The study is based on dynamical mean field…
Field dependent quasiparticles in models of strongly correlated electrons
J. Bauer, A. C. Hewson
In earlier work we showed how the low energy behavior of the symmetric Anderson model in a magnetic field could be described in terms of field dependent renormalized quasiparti…
Magnetic Field Effects on Quasiparticles in Strongly Correlated Local Systems
A. C. Hewson, J. Bauer, W. Koller
We show that quasiparticles in a magnetic field of arbitrary strength can be described by field dependent parameters. We illustrate this approach in the case of an Anderson imp…
