Numerical renormalization group can be used to disclose the rich physics in these systems. These problems include the impurity near the quantum critical point, the impurity imbedded in correlated environment, boundary field theory and boundary phase transition, the behavior of qubit under dissipation, and the dissipation effect on electron transport through quantum dots. Correlation induced localization effect, the Mott transition in transition metal oxides such as V2O3, organic materials, and optical lattices, etc. Study the effect of orbitals and phonons on the Mott transition in the transition metal oxides. Phase separation, striped phase, and the intrinsic charge inhomogeneity in the doped manganite and cooperate materials. Investigating their physical mechanism and the essential relationship between phase separation and the special properties of the materials, such as CMR and High Tc superconductivity. Diversity of symmetry breaking in the transition metal oxides where charge, spin and orbital degrees of freedom are all involved. Examples of such systems 4

5 are the Fe oxides and the doped manganite oxides. Investigate the complex interplay between different channels and find the mechanism that can stablize the specific long-range-ordered state observed in experiment. The manifest of quantum critical point in condensed materials. Special physical behavior, such as non-fermi-liquid behavior and power law behavior, can be found in systems near quantum critical point. Study the relationship between such behavior observed in real materials (such as heavy fermion system and high Tc superconductor) and the possible existence of certain quantum critical points. Study the properties of quantum critical point in certain theoretical models. Development of numerical methods including numerical renormalization group, quantum Monte Carlo, dynamical mean field theory and its extensions, and the equation of motion method. To overcome their respective shortcomings and limitations, and apply them in more extensive fields. 5
