Dynamical mean field theory for heavy fermion systems and transition metal oxides
Dynamical mean field theory for heavy fermion systems and transition metal oxides
Dynamical mean field theory investigations of strongly correlated models such as the periodic Anderson model and the Hubbard model in the normal paramagnetic phase have been carried out using diagrammatic perturbation theory based methods. Using results from such studies, dynamics and transport properties of several heavy fermion systems and transition metal oxides have been quantitatively explained and understood. Several issues such as universality and scaling, large and negative magnetoresistance, anomalous features in resistivity and optics have been highlighted. Two PhD theses have resulted from this work.
