Optical-spin coupling in the nitrogen-vacancy centre in diamond. Australia has made investment in the developing area of quantum information processing where information is stored and processed by manipulating the spin states in solids. One of the most promising materials for this purpose is diamond incorporating nitrogen-vacancy colour centres. The appeal with this material is that the processing can be faster and components smaller as the spins can be controlled by laser beams.

This project will exploit observations of phonon-based chemical contrast in the SHeM to determine the physics that underpins the imaging mechanism and use them to probe vibrational processes in condensed matter imaging. Imaging is an essential tool for the discovery, application and fabrication of new materials, structures and devices. However, many delicate structures are irrevocably degraded and changed when imaged using conventional microscopy. This team recently invented the scanning helium atom microscope (SHeM), which can image surfaces non-destructively with nanoscale resolution. They will use the SHeM to determine the new fundamental physics that underpins the imaging mechanism. Outcomes include turning SHeM into a tool that materials and biological scientists can use in laboratories worldwide.Read moreRead less
