David Hawthorn

David Hawthorn is a Professor at the University of Waterloo, affiliated with the Quantum Matter research group. His work focuses on the electronic and structural properties of quantum materials, particularly cuprate and nickelate superconductors. He employs advanced X-ray scattering techniques to investigate phenomena such as charge density waves, nematicity, and phase transitions in these systems. His research explores the interplay between superconductivity and competing orders, with a strong emphasis on understanding the fundamental physics of high-temperature superconductors.

Key areas of investigation include oxygen ordering effects in cuprates, strain-induced phase tuning, and the dynamics of electronic order parameters. Hawthorn’s studies often involve cutting-edge experimental methods such as resonant soft X-ray scattering and time-resolved spectroscopy. His contributions have advanced the understanding of electronic phase diagrams and emergent phenomena in complex oxides.

Notable research highlights include pioneering work on stripe-ordered cuprates, the discovery of novel superoxygenated phases, and the elucidation of orbital-selective electronic behaviors. His group, the Quantum Materials Spectroscopy Group, develops and applies advanced spectroscopic tools to probe quantum materials at atomic and electronic scales.
