Semiclassical action based on dynamical mean-field theory describing electrons interacting with local lattice fluctuations
Stefan Blawid, Gertrud Zwicknagl
We extend a recently introduced semiclassical approach to calculating the influence of local lattice fluctuations on electronic properties of metals and metallic molecular crystals…
The Kondo lattice model with correlated conduction electrons
Tom Schork, Stefan Blawid, Jun-ichi Igarashi
We investigate a Kondo lattice model with correlated conduction electrons. Within dynamical mean-field theory the model maps onto an impurity model where the host has to be determi…
A model of semimetallic behavior in strongly correlated electron systems
Stefan Blawid
Metals with values of the resistivity and the Hall coefficient much larger than typical ones, e.g., of sodium, are called semimetals. We suggest a model for semimetals which takes…
Theory of the temperature and doping dependence of the Hall effect in a model with x-ray edge singularities in d=oo
Mukul S. Laad, Stefan Blawid
We explain the anomalous features in the Hall data observed experimentally in the normal state of the high-Tc superconductors. We show that a consistent treatment of the local spin…
