Programm

In our International Research Training Group Electron-Electron Interactions in Solids, theoretical and experimental physicists work together with material scientists in four institutes in Marburg and in Budapest. Our collaboration covers sample preparation and characterization, the experimental investigation of magnetic, optical, and transport properties of correlated electron materials, and their theoretical investigation.
Our approach is strongly interdisciplinary because material preparation and characterization goes hand in hand with experimental studies and theoretical interpretation. Our research not only covers the application of established methods, we also put an emphasis on the design of advanced materials, on the set-up of new experimental techniques, and on the development of theoretical methods and numerical algorithms. These are important elements of our innovative research program.
Our innovative joint research efforts center around the following topics:
1. The development and application of the Gutzwiller variational approach, of static and dynamical mean-field theories, and of density-functional theory to strongly correlated electron systems
2. The development of the Density-Matrix Renormalization Group (DMRG) method in connection with quantum-information theory and various applications to low-dimensional systems, both for fundamental Hamiltonians) and for quasi one-dimensional materials.
3. The preparation and analysis of possible spintronic materials.
4. The preparation, experimental analysis, and theoretical interpretation of dynamical processes on two-dimensional structures.
