Our ability to control the electronic properties of materials, for instance at semiconductor interfaces, has had enormous scientific and technological implications. Recently, this concept has been extended to materials which possess inherently strong quantum many-body interactions, such as strongly correlated transition metal oxides, allowing us to synthesize artificial heterostructures which can harbor novel electronic or magnetic properties. I will describe some examples of our recent work in creating such systems using oxide molecular beam epitaxy (e.g. superlattices of colossal magnetoresistive manganites and atomically thin films of correlated nickelates) and investigating their electronic structure and interactions using angle-resolved photoemission spectroscopy.
