钚的电子关联强度

The Electronic Correlation Strength of Pu

摘要:

定义了一个电子量--关联强度,它是理解强关联电子材料的性质和发展趋势的必要步骤。作为一个测试案例,这适用于元素钚的不同阶段。在GW近似中,我们意外地发现了一个“通用”的缩放关系,其中由于相关效应而导致的f-电子带宽减小被示出为仅取决于局部密度近似带宽,并且在其他方面与晶体结构和晶格常数无关。

英文摘要:

An electronic quantity, the correlation strength, is defined as a necessary step for understanding the properties and trends in strongly correlated electronic materials. As a test case, this is applied to the different phases of elemental Pu. Within the GW approximation we have surprisingly found a "universal" scaling relationship, where the f-electron bandwidth reduction due to correlation effects is shown to depend only on the local density approximation bandwidth and is otherwise independent of crystal structure and lattice constant.
