Stephen Hayden is Professor of Physics at the H. H. Wills Physics Laboratory, University of Bristol. He is an experimental condensed matter physicist interested in strongly correlated electron systems such as layered transition metal oxides. His research uses scattering (neutrons, x-rays) and thermodynamic probes to understand the electronic properties and the nature of any ordered states in these diverse materials. Prof. Hayden is known for his work on high-temperature cuprate superconductors, his work has revealed, how the structure and strength of the spin excitations in these materials varies across their doping-temperature phase diagrams. The results provide evidence for the high-energy excitations required by magnetically mediated theories of high temperature superconductivity. More recently he has studied charge order in cuprate superconductors investigating the detailed structure of the charge density waves and importantly how they interact with superconductivity as the latter is tuned with high magnetic field.
Professor Hayden studied for his BA at the University of Cambridge. He stayed in Cambridge working with Gilbert Lonzarich for his PhD and a postdoctoral fellowship. He them held a physicist position at the Institut Laue-Langevin, Grenoble. In 1991, he moved to the University of Bristol where he is now a Professor.
Professor Hayden is a fellow of the Institute of Physics. His awards include the IOP Mott Prize (2019) and a Wolfson-Royal Society Merit Award (2007). He has served on neutron and x-ray allocation panels across Europe, worked closely with ISIS and Diamond to develop new instruments and is director of the EPSRC Centre for Doctoral Training in Condensed Matter Physics run by the Universities of Bristol and Bath.
