Applications are invited for a postdoctoral research position in theoretical condensed matter physics. The successful candidate is expected to have a PhD in condensed-matter theory and will work in the group of Professor Mark Dykman in the Department of Physics and Astronomy at Michigan State University. She or he will participate in the research of electrons on the helium surface, with the emphasis on the spin dynamics, decoherence mechanisms, and the operation of spin-based qubits. The initial appointment will be one year, but is renewable for an additional year.
