Hierarchical Extension of Quantum Models with Inverse-Square Interactionactional quantum Hall effect (FQHE). Under the chiral constraint the model describes characteristic properties of edge states for the FQHE. In particular the excitation spectrum is classified in terms of the topological-order matrix of the FQHE.

Elementary Excitations for Impurity Models the Kondo problem: the ordinary Anderson model, the orbitally degenerate Anderson model and the multi-channel Kondo model. The calculations for the multi-channel Kondo model are further extended to the case at finite temperatures by means of Yang and Yang’s method developed in one-dimensional interacting boson systems.

Phase Diagram of the One-Dimensional Kondo-Lattice Modelesults interpolating those limits. In one dimension there are three phases: a ferromagnetic metallic phase, a paramagnetic metallic phase and an insulating spin-liquid phase. Emphasis is placed upon the strong coupling limits which are important to understand the properties of these phases.
