摘要：

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.
