通过研究 LaNi1-xMxO3(M = Mn 和 Fe),我们发现在金属-绝缘体转变过程中存在强相互作用效应的情况下,光谱函数的特征演化随着无序性的增加而增加。我们将这些结果与同时存在无序和相互作用的现有电子结构理论进行讨论。
Investigating LaNi1-xMxO3 (M = Mn and Fe), we identify a characteristic evolution of the spectral function with increasing disorder in the presence of strong interaction effects across the metal-insulator transition. We discuss these results vis-a-vis existing theories of electronic structure in the simultaneous presence of disorder and interaction.
