简介: |
In this talk, I will review the main progress in multi-band Hubbard model in recent years. Including the orbital degree of freedom in Hubbard model will generate several new features, such as the coexistence of the itinerant and local moment features for the electrons, which are impossible for the single band systems. I will also explain in detail that the interplay between the orbital and spin fluctuation will lead to non-Fermi liquid behavior in these systems in a quite wide temperature range. |
