45th IFF Spring School

Computing Solids: Models, Ab-initio Methods and Supercomputing

10 -21 March 2014 in Jülich, Germany



The IFF Spring School 2014 will provide a comprehensive introduction to modern concepts, theories and methods enabling the theoretical description of many-electron systems. The hallmark of this year’s school is in the concept of discussing density functional theory type ab-initio approaches as well as specialized
many-body techniques for strongly correlated systems emphasizing the new opportunities provided by high-performance computers with advanced architectures. The school links these three aspects to the study of emergent properties of solids and non-equilibrium quantum transport. The guiding principle for the selection of the specialized subjects was their timeliness and the expertise of the scientific institutes involved. The school will start with introductory lectures on the many-electron problem. Basic lectures will introduce the different methodologies but will also bring in cutting edge research in the field. The formulation of realistic model Hamiltonians links density functional theory to the many-body methods. The school will move on to discuss solutions to the many-body problem of model systems, either analytically using renormalization group techniques, or numerically using different computational implementations.  

The School will then advance to the calculation of different materials and physical effects. One emphasis is the quantum and topological transport properties. The School also includes lectures on computational topics addressing the recent and future advances in computer architecture and technology. These lectures will especially focus on how the computational resources can be exploited for the simulation of complex materials, for example, via parallel programming or how large computing resources change the paradigm of materials research, for example by database oriented material design approaches.

The topics of the lectures cover:

  • Density functional theory and methods
  • Many-body perturbation theory
  • Model Hamiltonians
  • Renormalization group techniques
  • Berry phase physics and Wannier functions
  • Materials Informatics and design
  • Nonequilibrium quantum-transport and open systems
  • Simulation techniques
  • Parallel Computing
  • Application to graphene, magnetic skyrmions and pnictides

The IFF Spring School is organized in close collaboration with universities, research institutions and industry. The School offers around 45 hours of lectures plus discussions as well as the opportunity to visit the participating institutes at the Forschungszentrum Jülich. All lectures will be given in English. Each registered participant will receive a copy of the lecture notes (in English), which contain all the material presented during the school.
