The chair of Numerical Mathematics for High-Performance Computing at the Institute for Applied Mathematics and Numerical Simulation searches for a Ph.D. candidate (or postdoc) to run a project on the a posteriori error estimation of nonlinear eigenvalue problems arising in Density-Functional Theory (DFT) of electronic structure calculation. The developed methods and estimators will be implemented and tested in the open-source DFTK software package, written in Julia. Your profile • Excellent Msc (or PhD) degree in applied mathematics. • Specialization in applied mathematics and numerical analysis. • Strong interests in application to electronic structure calculation. • Interest and skills in the implementation of numerical methods. What we offer • TV-L 13 75% position for at least 3 years (TV-L 13 100% position for post-doc applications). • An international and interdisciplinary research environment.
