David Hawthorn
Biography
The Quantum Materials Spectroscopy group, led by Dr. Hawthorn, studies Quantum Materials using resonant soft x-ray scattering and x-ray absorption spectroscopy at synchrotrons such as the Canadian Light Source. We use these tools to investigate intertwined order in Quantum Materials and shed light on the long-standing mysteries of high temperature superconductors.
