Oxide Interfaces: a New Era of Correlated-Electron Physics

Carefully controlled interfaces between two materials can give rise to
novel physical phenomena and functionalities not exhibited by either of
the constituent materials alone. Prominent examples include the quantum
Hall effect in semiconductor heterostructures and the ?giant
magnetoresistance? effect in superlattices of simple metals. Using modern
synthesis methods, it is now possible to engineer interfaces between
transition metal oxides with atomic-scale precision. We will give an
overview of the physics at work in the bulk of selected transition metal
oxides, where strongly correlated electrons generate interesting quantum
many-body phenomena such as unconventional superconductivity and
?colossal magnetoresistance?. We will then provide a glimpse of novel
interface physics in heterostructures of these materials. 

Time: 4:15pm
Place: Room 10-250
Refreshments will be served in the Physics Undergraduate Lounge (8-329)
at 3:45pm
