We compare the trends on the strength of electronic correlations across the different phases of elemental Pu focusing on its site and orbital dependence, using a combination of density functional theory (DFT) and dynamical mean field theory (DMFT) calculations within the vertex corrected one crossing approximation. We find that Pu-5$f$ states are more correlated in $δ$-Pu, followed by some crystallographic sites in $α$ and $β$ phases. In addition, we observe that Pu-5$f_{5/2}$ and Pu-5$f_{7/2}$ orbital differentiation is a general feature of this material, as is site differentiation in the low symmetry phases. The Pu-5$f_{5/2}$ states show Fermi liquid like behavior whereas the Pu-5$f_{7/2}$ states remaining incoherent down to very low temperatures. We correlate the correlation strength in the different phases to their structure and the Pu-5$f$ occupancy of their crystallographic sites.
Hall coefficient signals orbital differentiation in the Hund's metal Sr$_2$RuO$_4$
Sr $_2$ RuO $_4$的霍尔系数$R_H$呈现出两个符号反转的非单调温度依赖性。我们表明，这种令人费解的行为是两个交叉的签名，这是关键的物理材料。$R_H$的增加和冷却后的第一个符号变化与进入相干准粒子制度的交叉相关，该制度具有强的非弹性散射率的轨道分化。在较低温度下的最终减少和第二个符号变化是由从非弹性散射到杂质主导散射的交叉驱动的。这种定性的图片支持的定量计算$R_H(T)$使用玻尔兹曼输运理论结合动力学平均场论，考虑到自旋轨道耦合的影响。我们的见解揭示了霍尔系数的温度依赖性强轨道分化的材料，在洪德的金属中观察到的。
