| Research Abstract |
We studied the many-body electronic states in metals with orbital degree of freedoms. The main objects are (i) spin Hall effect and anomalous Hall effect driven by the Berry phase due to orbital degree of freedoms and spin-orbit coupling (orbital Berry phase), and (ii) the mechanism of superconductivity and anomalous transport phenomena due to orbital fluctuations driven by Coulomb interaction.
