Theory of the Temperature and Doping dependence of the Hall effect in a model with X-ray edge singularities in d =

By Mukul S. Laad and 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 fluctuations in a model with x-ray edge singularities in d = ∞ reproduces the temperature (T) and the doping dependence (x) of the Hall constant RH as well as the Hall angle in the normal state. The model has also been invoked to justify the marginal Fermi liquid (MFL) behavior, and provides the first consistent explanation of the Hall anomalies for a non-Fermi liquid in d =∞.
