Job description:PhD Position - Lattice field theory

The Jülich Supercomputing Centre (JSC) operates JUPITER, Europe's first Exascale supercomputer and runs JUNIQ, the first European user infrastructure of quantum computing. Within the division HPC for Quantum Systems, the Simulation and Data Laboratory (SDL) Numerical Quantum Field Theory aims to understand the properties of strongly interacting/correlated matter such as the spectrum of QCD, and develops algorithms and implementations for various high-performance computing (HPC) systems.

The Institute for Advanced Simulation - Theory of Strong Interactions (IAS-4) deals with strong interactions in the non-perturbative arena, in particular with the structure and dynamics of hadrons and atomic nuclei. Of particular interest is the spectrum of quantum chromodynamics. Fundamental tools are Monte Carlo simulations, which are also successfully applied to strongly correlated electronic systems.

Within the Cluster of Excellence "

Color meets Flavor

" (CmF), JSC and IAS-4 offer a PhD opportunity with a focus on exotic hadrons.

Your Job

You will be

• performing simulations of lattice quantum field theory,
• developing analysis methods and tools and simulation software,
• analyzing, publishing and presenting the results,
• while collaborating with other group members and collaborators and, in particular, members of the Cluster "Color meets Flavor"

Your Profile

• Completed Master`s degree in physics or similiar
• Knowledge of lattice quantum field theory
• Experience with programming languages, in particular C/C++/Python
• Experience with Linux and high-performance computing
• Willingness to contribute with talks to international conferences
• Willingness to participate in courses and tutorials
• Very good command of written and spoken English with extensive vocabulary is required (at least B2 level according to the CEFR
