Jobbeschreibung

Research Position (Postdoc) (m/f/d)

ID: Wiss26247

• starting: as soon as possible
• fulltime
• salary according to Remuneration level 13 TV-L
• fixed-term

Prof. Dr. Malte Rösner’s group studies the properties of novel correlated quantum materials. A particular focus is on synergistic collaboration with groups in experimental physics. To this end, ab initio calculations are combined with modeling concepts and numerical many-body methods to enable material-specific theoretical predictions.

Tasks

• theoretical scientific work/research on (strongly) correlated materials (95 %)
• participation in self-governance tasks (5 %)

Benefits and Contract Details

• salary according to Remuneration level 13 TV-L
• fixed-term (2 years) (§ 2 (1) sentence 2 of the WissZeitVG; in accordance with the provisions of the WissZeitVG and the Agreement on Satisfactory Conditions of Employment, the length of contract may differ in individual cases)

• variety of health, consulting and prevention services
• reconcilability of family and work
• supplementary company pension
• flexible working hours

Your Profile

• completed university degree (Master or equivalent) in Physics
• completed PhD in Theoretical Solid-State Physics
• experience in the ab initio (material-specific) description of materials, for example using density functional theory and/or GW theory
• experience in applying downfolding methods, for example cRPA, mappings to minimal spin models, or comparable approaches
• good command of written and spoken English
• extensive knowledge of Theoretical Solid-State Physics
• ability to work independently, take initiative, and demonstrate commitment
• ability to work effectively as part of a team

Preferred experience and skills

• experience in describing electronic, optical, and/or magnetic correlation effects (e.g., using GW, BSE, DMFT, or magnetic simulations)
• experience in ab initio descriptions of magnetic materials
• experience in programming in Python and/or C++ and/or Fortran
• experience working with high-performance computer systems
• experience supervising bachelor’s and master’s theses
• experience supervising exercises/tutorials
