Realistic theories of heavy electron and other strongly correlated materials.

摘要

Research on the following topics is summarized: non-perturbative treatments of multi-channel Kondo models, non-perturbative treatments of multi-band models for the quadrupolar fluctuation model of the cuprates, extension of the two-channel Kondo model to other materials and treatment of the infinite-dimensional Hubbard model within the Non-crossing approximation. Data on the specific heat of Y(sub 0.8)U(sub 0.2)Pd(sub 3) and the c-axis susceptibility and specific heat of U in ThRu(sub 2)Si are shown. 5 figs., 84 refs.
