The department uses neutron and X-ray diffraction and spectroscopy as well as optical spectroscopy and Raman scattering to explore the structure and dynamics of materials with strong electron correlations. We also have a strong effort in the development of new spectroscopic methods. As the close collaboration between experimentalists and theorists is essential for the progress in this field, a small theory group operates within the department.
Recent experimental and theoretical developments have brought fresh excitement to the field of high-temperature superconductivity. The February 12 issue of Nature contains a review accessible to a general audience.
Alex Frano received the Ernst-Eckhard-Koch Prize of the Helmholtz Zentrum Berlin for his Ph.D. thesis on resonant x-ray scattering from metal-oxide superlattices. He is now a postdoc at the University of California at Berkeley.
A new technique that allows Raman scattering from 10 nm thin metal-oxide films has shown that spin and charge order in nickelates can be tuned by epitaxial strain. The paper appeared as an Editor's Choice in Physical Review Letters.
