Towards Material Design Using Strongly Correlated Electron Systems
Coordinators: Antoine Georges, Gabriel B. Kotliar, Sergey Savrasov
Scientific Advisors: Jim W. Allen, Zachary Fisk, Andrew J. Millis, Nicola Spaldin
Physical understanding, materials synthesis, experimental techniques and theoretical methods have progressed to the point that we can contemplate rational design of materials with novel electronic properties (e.g. high transition temperature magnetism or superconductivity). This program will bring together scientists from various communities (many-body theory, electronic structure, condensed matter theory and experiment, materials science) working in this area to establish this field, its techniques, problems and methods.
The focus will be on the issues raised by properties of "strongly correlated" metallic states, such as optimizing superconducting and magnetic transition temperatures or transport properties. The activities of the program will be along two directions: (i) new methodological developments, (ii) system specific theoretical studies of materials. Vigorous participation by experimentalists will connect the results of the workshop to the development of actual new materials.
Among the methodological developments, the following problems will be formulated and addressed
- Derivation of suitable low energy Hamiltonians
- Theories of critical temperatures
- Description of crossovers and evaluation of crossover scales
- Interface between many-body methods and electronic structure approaches
Among the classes of materials to be investigated, we highlight:
- Heavy fermions
- Cerium and Cerium-based 115's
- Magnetically-ordered transition metal oxides
- Cuprate-based high temperature superconductors
- Iron Pnictides
- Cobaltates and Ruthenates
- Actinides and actinide-based 115's
- Correlated heterostructures
- Organic salts
Conference: There will be an associated conference entitled Novel Correlated Materials to be held February 8 – 12, 2010.
