As member of the Helmholtz Association of German Research Centers, the HZDR employs about 1,400 people. The Center's focus is on interdisciplinary research in the areas energy, health and matter.

The Institut CASUS

As part of the Institute, the Department of FWU invites applications as

Ph.D. Student (m/f/d): Electronic Transport Properties and Nonequilibrium Phenomena in Warm Dense Matter

The position will be available immediatly. The employment contract is limited to 3 years.

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-Rossendorf, 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. CASUS is located in the heart of Görlitz at the border between Germany and Poland. The CASUS start-up phase is hosted by the Helmholtz-Zentrum Dresden-Rossendorf and is financed by the Federal Ministry of Education and Research and the Saxon State Ministry of Science and Art.
The Department on Matter under Extreme Conditions is looking for a Ph.D. student interested in developing and applying numerical modeling techniques for Electronic Transport Properties and
Nonequilibrium Phenomena in Warm Dense Matter. Consideration of candidates will begin immediately and will continue until the position is filled.

The Scope of Your Job

You are expected to apply high-fidelity electronic structure methods (DFT-MD and TDDFT) to compute electronic transport properties (dynamical structure factor, electrical conductivity, and stopping power) in warm dense matter. You will devise a theoretical formalism and develop modeling techniques to capture the physics in high-fidelity data from TDDFT within a surrogate model for the numerical modeling of warm dense matter that is computationally more efficient. You will implement the surrogate model in a suitable software package and validate it against high-fidelity data. You will also complement state-of-the-art fluid dynamics and magneto-hydrodynamics codes with on-the-fly data from high-fidelity simulations and 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. 

Tasks:

  • Compute electronic transport properties to support the diagnostics of x-ray scattering experiments in warm dense matter using high-fidelity electronic structure methods (DFT-MD and TDDFT)
  • Devise the formalism and modelling techniques to capture the physics in high-fidelity data within a surrogate model
  • Implement the surrogate model in a suitable software package
  • Validate against electronic transport properties from high-fidelity calculations and experiments
  • Extend the surrogate model by implementing non-equilibrium methodologies and establishing a link to state-of-the-art fluid dynamics and magnetohydrodynamics codes
  • Publish your results in academic, peer-reviewed journals
  • Present your results at scientific meetings

Requirements:

  • 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 of training according to the Helmholtz Doctoral Guidelines
  • Salary and social benefits in conformity with the provisions of the Collective Agreement TvöD-Bund
  • 30 Vacation Days per year
  • Company pension scheme (VBL)
  • A good work/life balance for which we offer assistance in the form of:
    • possibility to work part-time

    • flexible working hours

    • in-house health management

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