The mission of the Quantum Materials Lab (QML) is the fabrication and study of novel complex systems and nanostructured materials. The QML members are associated with the UBC research groups lead by Prof. G.A. Sawatzky and Prof. A. Damascelli within the Department of Physics & Astronomy, and Dr. N. Ingle of AMPEL. The QML is located in the AMPEL Building at UBC.

The QML was established to enable a comprehensive theoretical and experimental approach to the physics of novel quantum materials. Each research group contributes a specific expertise, which makes the QML a unique collaborative environment for the study of these novel materials and structures. This also furnishes an extremely rich and varied experience for students and post-docs.

The research program is concentrated on the study of the electronic structure of the strongly correlated electron systems, in bulk as well as ultra-thin film form. We use both high-energy and high-resolution spectroscopies, in combination with many-body theoretical modeling, to develop a microscopic description of the macroscopic physical properties of solids.

The research activity focuses on the study of the low-energy electronic structure and, in particular, of the interplay between the spin, charge, and orbital degrees of freedom in novel complex systems, and one and two-dimensional nanostructures. Our primary tools are angle-resolved photoemission spectroscopy (so-called ARPES) and other highly-advanced synchrotron-based spectroscopies.

This research program is primarily concerned with the growth of novel complex oxide thin films. In particular we are interested in understanding how defects -- both point defects and extended defects such as interfaces and surfaces -- can be used to modify the electronic properties of oxides.
