This activity supports basic research at both universities and DOE national laboratories in condensed matter physics and materials physics using electron, neutron, and x-ray scattering capabilities. Research includes experiment and theory that seeks to achieve a fundamental understanding of the atomic, electronic, and magnetic structures and excitations of materials as well as the relationship of these structures and excitations to the physical properties of materials. Also supported is the fundamental dynamics in complex materials, correlated electron systems, nanostructures, and novel systems using advanced ultrafast spectroscopy, diffraction and microscopy. The emphasis is on using time-domain approaches to provide new understanding of complex behavior, emergent phenomena, and exotic properties in condensed matter. Another increasingly important part of the portfolio is studying the nature of materials at the nanoscale including ordering fluctuations, and the structure and composition of inhomogeneities such as defects, interfaces, surfaces, and precipitates. The continuing development and improvement of next-generation x-ray and neutron scattering instrumentation including a full range of elastic, inelastic, and imaging techniques as well as ancillary technologies such as novel detectors, sample environment, data analysis, and technology for producing polarized neutrons is also supported. Advancing the state of the art of electron beam and scanning probe techniques and instrumentation for quantitative microscopy and microanalysis is an essential element in this portfolio. The increasing complexity of energy-relevant materials currently of interest such as superconductors, semiconductors, and magnets requires ever more sophisticated scattering techniques to extract useful knowledge and to develop new theories for the behavior of these materials. X-ray, neutron, and electron scattering are the primary tools for characterizing the atomic, electronic, and magnetic structures of these materials.
