At the University of Kassel, Department of Mathematics and Natural Sciences, Institute of Physics - Department of Theoretical Physics II (Prof. Dr. Martin Garcia), the following position is available as soon as possible:

Research Assistant (m/w/d), EG 13 TV-H, temporary, part-time (currently 20 hours per week).

Part-time position with half the working hours of a full-time employee. This is a fixed term-position of three years in the framework of the DFG-Grant “Large-scale atomistic simulations of laser-excited bismuth with density functional theory accuracy: unified description of nonthermal and thermal ultrafast relaxation effects“ (§ 2 Abs. 2 WissZeitVG). Opportunity for PhD work is given.

The department of Theoretical Physics II has long experience in modeling laser-material interactions and is a world leader in the development of high-precision interatomic potentials to describe laser excitations using machine learning. The department has excellent computer resources (including its own computer cluster with GPUs) and access to high-performance computers in Germany.


  • Development of a model to describe the femtosecond laser pulse excitation of solids, taking into account surface effects on experimentally accessible length and time scales
  • The dynamics of the atomic lattice, the bonding electrons, as well as the laser-generated free electron-hole pairs shall be considered, taking into account electron-phonon- and spin-orbit coupling. Strong electron correlations that may arise should also be included in the model
  • Modeling will be performed using an extension of the TTM-MD ("two temperature model molecular dynamics") method with density functional theory accuracy
  • Scientific collaboration in research and teaching in the field of Solid State Theory and Ultrafast Phenomena


  • Completed course of academic study (Master degree) within the fiel of in Physics with theoretical emphasis completed with very good marks. The required degree must be received no later than the hiring date
  • Solid background in Theoretical Solid State Physics
  • Very good English skills
  • Very good programming skills


  • Background in parallel computing
  • C++ and/or Python
  • Knowledge of light-matter interaction
  • Good analytical skills
  • Knowledge in application of machine learning methods
