Pressure is opening up broad new vistas on superconductivity from simple elements to complex materials and the creation of new electronic and magnetic materials.
A wide range of theoretical techniques will be applied to study the new materials found in our experiments, both to predict new materials for experimental study, and to understand the origins of observed material behavior. Close coupling of theory and experiment is one of the strengths of the EFree Center. This synergy is important because measurements of high P-T behavior of a wide variety of materials provide stringent tests of theory, while theory can stimulate and direct experimental activities.
Studies of conventional and novel metals provide important challenges and opportunities that are central to energy research. Flexibility in composition translates to wide variability throughout the range of chemical and physical properties, particularly as we explore the pressure dimension in crystalline metals and alloys as well as metallic glasses. The high P-T response of metallic structural components of advanced energy systems need to be understood at the multiscale in order to enhance performance.
