題名: | Quantum Renormalization of the Spin Hall Effect | 作者: | 郭光宇 Guo, Guang-Yu |

We show, for the first time, that the SOI is strongly renormalized by the quantum spin fluctuation. Based on this mechanism, we can explain why the gigantic spin Hall effect in Au with Fe impurities was observed in recent experiments, while it is not visible in the anomalous Hall effect. In addition, we show that the SOI is strongly renormalized by the Coulomb correlation . Based on this picture, we can explain past discrepancies in the calculated orbital angular momenta for an Fe impurity in an Au host. | 關聯: | Physical Review Letters, 105(8), 086401 | 資料來源: | http://link.aps.org/doi/10.1103/PhysRevLett.105.086401 | 資料類型: | article | DOI: | http://dx.doi.org/10.1103/PhysRevLett.105.086401 |
