David G. Hawthorn Condensed matter physicist

David Hawthorn is an expert in experimental condensed matter studies, specifically using X-ray scattering and spectroscopy to investigate high-temperature superconductors and other quantum materials. His recent research highlights include the invention of a new method for measuring the absorption of x-rays in materials; the development of an instrument for resonant x-ray scattering at the Canadian Light Source; and investigations of charge-density wave order in high-temperature superconductors using resonant X-ray scattering.
