Welcome to our group homepage! The group is headed by Prof Duncan Steel, the Robert J Hiller Professor of Electrical Engineering and Computer Science, who also holds a joint apointment in the Physics department at the University of Michigan, Ann Arbor. He is also a Research Professor in Biophysics where he runs the Protein Folding and Stability Research Lab.
Research in the group focuses on the use of coherent optical interactions to study, control, and manipulate the quantum properties of semiconductor heterostructures. Over the past few years, the group has been able to demonstrate astonishing atom-like phenomena in a complex condensed matter system. This has opened up the possibility of using such semiconductor heterostructures in schemes of making a scalable quantum computer. Recently we have also begun work on doing spectroscopy using special light beams which carry orbital angular momentum. We encourage you to explore our projects by by clicking on the links above. For any technical questions or inquiries about opportunities in the group, feel free to contact any of the Graduate students or Prof Steel himself.
