PhD Student (m/f/d) - Surrogate Models for Nonequilibrium Phenomena in Warm Dense Matter

A member of the Helmholtz Association of German Research Centers, the HZDR employs about 1,200 people. The Center's focus is on interdisciplinary research in the areas energy, health and matter.

The Center for Advanced Systems Understanding (CASUS) is a German-Polish research center for dataintensive digital systems research. We combine innovative methods from mathematics, theoretical systems research, simulations, data science and computer science to provide solutions for a range of disciplines - materials science under ambient and extreme conditions, earth system research, systems biology and autonomous vehicles.

CASUS was jointly founded in August 2019 by the Helmholtz-Zentrum Dresden-Rassendorf, the Helmholtz Centre for Environmental Research, the Max Planck Institute of Molecular Cell Biology and Genetics, the Technical University of Dresden and the University of Wroclaw.

The Department on Matter under Extreme Conditions is looking for a PhD student (m/f/d) interested in developing Surrogate Models for Nonequilibrium Phenomena in Warm Dense Matter.

The position will be available from now. The employment contract is limited to three years.

The Scope of Your Job:

You are expected to develop a time-dependent average-atom model for the numerical modeling of electronic transport properties (dynamical structure factor, electrical conductivity and stopping power) in warm dense matter. Based on static average-atom models, you will implement your time-dependent methodology in a suitable software package and validate it against high-fidelity data from DFT-MD and TDDFT simulations. Furthermore, you will use the surrogate model as a testing ground to implement novel methodologies for modeling nonequilibrium behavior beyond local thermal equilibrium. You will also complement state-of-the-art fluid dynamics and magnetohydrodynamics codes with on-the-fly data from your surrogate model. In collaboration with our partners at international research institutions and the Helmholtz association, your surrogate model will support the successful characterization of HED phenomena generated in laboratories such as coherent light sources and pulsed power facilities.


  • devise a formalism and techniques for time-dependent average-atom models and implement the methodology in a suitable software package

  • validate against electronic transport properties from DFT-MD and TDDFT calculations

  • extend the time-dependent average atom model by implementing nonequilibrium methodologies and establishing a link to state-of-the-art fluid dynamics and magnetohydrodynamics codes

  • compute electronic transport properties to support the diagnostics of x-ray scattering experiments in warm dense matter

  • publish your results in academic, peer-reviewed journals

  • present your results at scientific meetings


  • very good Master's degree in physics, theoretical chemistry or in a related subject

  • a solid background in mathematics, theoretical and computational physics or in a related subject

  • experience in quantum mechanics or many-body theories

  • excellent programming skills in languages such as Fortran, Python or C/C++

  • experience in methods development or data generation with electronic structure codes (such as VASP, Quantum Espresso, Elk)

  • strong motivation to work in a collaborative environment

  • excellent communication skills in English and in a professional context (presentation of research results at scientific meetings, colloquial discussions, writing of manuscripts)

We offer:

  • a vibrant research community in an open, diverse and international work environment

  • scientific excellence and high quality

  • broad national and international science networks

  • salary and social benefits in conformity with the provisions of the Collective Agreement TVöD-Bund (30 vacation days per year, company pension plan)

  • a good work/life balance for which we offer assistance in the shape of:

    • in-house health management

    • flexible working hours

Kindly submit your completed application (including cover letter, CV, diplomas/transcripts, etc.) only via our Online-application-system.
