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.
The interplay between charge density waves and high-temperature superconductivity is currently under intense investigation .Resonant x-ray scattering experiments have now shown that interfaces with manganates greatly enhance charge density wave formation in cuprate superconductors, over a remarkably large length scale of tens of nanometers. Long-range proximity effects induced by heterointerfaces thus offer a powerful method manipulate the interplay between different collective phenomena in metal oxides.
