Orbitronics in Silicon — •Gabriel Aeppli — London Centre for Nanotechnology, University College London, UK

Control of magnetic interactions as well as localised spin sates is a prerequisite for spin-based quantum computing. Interactions can be induced via photons or exchange interactions mediated through atomic orbitals. We have consequently carried out optical and scan probe measurements demonstrating control over donor impurity orbitals in silicon and at its surface. The experiments are analogous to experiments performed in atom traps, where silicon plays the role of the vacuum and the impurity that of the atoms.
