| Research Abstract |
A single molecule on a metallic surface is one of intriguing materials in which the Kondo effect occurs. We found that the novel type of Kondo effect arising from the entanglement of orbital and spin degrees of freedom emerges in Fe-phthalocyanine molecule on Au(111). The origin of this spin+orbital Kondo effect is local symmetry arising from the combination between molecular framework and adsorption geometry. These results indicate the possibility to construct unique many-body electronic and spin states at surface by utilizing molecular characteristic.
