45th IFF Spring School

Computing Solids: Models, Ab-initio Methods and Supercomputing

10 -21 March 2014 in Jülich, Germany


The IFF Spring School & Computational Materials Physics in Jülich

The IFF Spring Schools were first brought into being in 1970 by the “Institut für Festkörperforschung” (IFF). Since then, they have made it possible for students and young scientists to gain a two-week insight into a current topic related to condensed matter physics. In 2011, IFF was dissolved as part of a restructuring process within Forschungszentrum Jülich, and new institutes, namely the “Peter Grünberg Institut” (PGI), the “Jülich Centre for Neutron Science” (JCNS) and the “Institute of Complex Systems”(ICS) were established. Together with the “Institute for Advanced Simulation” (IAS), they will continue to coordinate the IFF Spring Schools. The 45th Spring School 2014 will be organized by PGI-1/IAS-1 “Quantum Theory of Materials” together with the Theoretical Solid State Physics Group from the RWTH Aachen University.

Forschungszentrum Jülich has a long track record of advancing research in the field of computational materials physics and materials science. At a very early stage, scientists here recognized the importance of computer simulation as a source of knowledge in condensed matter physics. With the advent of peta-flop computing based on new architectural concepts, scientific computing is transforming to simulation sciences. Together with the Jülich Supercomputing Centre (JSC), the German Research School for Simulation Sciences (GRS), established under the umbrella of the Jülich-Aachen Research Alliance (JARA), and the recently founded Institute for Advanced Simulation (IAS), Forschungszentrum Jülich is home to a research triangle where education, different research disciplines together with methodical and technological competences are combined to manage the future challenges in simulation sciences.

The Institute “Quantum Theory of Materials” develops conceptual and computational methods based on density-functional theory. It supports an “ab initio” simulation laboratory. Computational materials science research is established by combining first-principles results with dynamical and statistical methods (molecular dynamics, Monte Carlo). The institute focuses on the analysis and computation of electronic properties of solid-state systems relevant for nanoelectronics (spintronics, nanoionics, complex magnetism, organic molecules) and energy.

The development of quantum many-body methods and their application in model systems of correlated electrons has a long history at the physics department of RWTH Aachen University. Nowadays, the department is split into the institutes of Theory of Statistical Physics and Theoretical Solid State Physics. The research pursued in the former is focused on correlation effects in mesoscopic systems including the rapidly developing field of non-equilibrium phenomena, using renormalization group-based approaches. In the latter, such methods as well as numerical tools (e.g. quantum Monte Carlo) are used to investigate the physics of correlated materials.
