Konstanz

University of Konstanz


The University of Konstanz (UKon) is one of the nine Universities of Excellence in Germany. The Department of Physics has intense activities in the area of solid state physics and, especially, nanophysics, parts of which are funded within the German Research Foundation through the Collaborative Research Center SFB767, “Controlled Nanosystems: Interaction and Interfacing to the Macroscale”. The group of Prof. Dr. U. Nowak has a long lasting experience with computer simulations of magnetic material properties, especially spintronics and spin dynamics, modelling the response of the magnetic system to laser pulses and spin-polarized currents. The group has also worked on certain aspects of multiscale modelling, an effort to link ab-initio calculations, spin model simulations, and large-scale micromagnetic methods. These calculations are currently performed on the high-performance computer cluster of the group (136 compute nodes with 3GHz, 0.29 Terabyte main memory, 0.34 Teraflop/s).

 

Role in the Network

UKon will lead the atomistic spin modelling providing its expertise on spin models as well as multi-scale modelling. Project relevant numerical methods currently used in the applicant’s group include Monte Carlo simulations, numerical solutions of stochastic differential equations, and micromagnetic modelling. Modern and highly optimised computational approaches will be provided, including parallel computations of Fast Fourier Transformations to scale down the numerical effort.
