Interfaces between dissimilar correlated oxides can offer devices withversatile functionalities. In that respect, manipulating and measuring novelphysical properties of oxide heterointerfaces are highly desired. Yet, despiteextensive studies, obtaining direct information on their momentum-resolvedelectronic structure remains a great challenge. This is because most correlatedinterfacial phenomena appear within a few atomic layers from the interface,thus limiting the application of available experimental probes. Here, weutilize atomic-scale epitaxy and photoemission spectroscopy to demonstrate theinterface control of correlated electronic phases in atomic-scaleruthenate--titanate heterostructures. While bulk SrRuO$_3$ is a ferromagneticmetal, the heterointerfaces exclusively realize three distinct correlatedphases in the single-atomic-layer limit. Our theory reveals that atomic-scalestructural proximity effects lead to the emergence of Fermi liquid, Hund metal,and Mott insulator phases in the quantum-confined SrRuO$_3$. These resultshighlight the extensive interfacial tunability of electronic phases, hithertohidden in the atomically thin correlated heterostructure.
