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

• performing simulations of lattice quantum field theory
• developing analysis methods and tools and simulation software
• analyzing, publishing and presenting the results
• 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 similar
• 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), ideally supported by a certificate confirming the language level. Knowledge of the German language is not mandatory (language courses are offered)
• Structured and systematic working style and ability to work cooperatively in international teams

Our Benefits for You

• Team & Environment: You will work in an exciting research environment within the research centre Juelich, Bonn University, the Cluster CmF, and the CRC NuMeriQS
• Research & Infrastructure: Access to and discretionary resources on the latest HPC Systems, such JUWELS or the exascale system "JUPITER"
• Networking & Exchange: The opportunity to participate in international conferences and project meetings as well as an opportunity for a fully funded extended international research stay
• Work-life balance: We offer flexible working hours to help you balance your professional and personal life. You also have the option of flexible working (in terms of location), which is generally possible after consultation and in line with upcoming tasks and (on-site) appointments
• Annual Leave: You get 30 days of annual leave
• Knowledge & Development: Your professional development is important to us – we support you specifically and individually e.g., through training and networking opportunities specifically for doctoral candidates (JuDocS). As well you will have access to support structures at Bonn University, such as the Bonn Graduate Center.
• Health & well-being: Your health is important to us. You can look forward to a comprehensive company health management programme with a wide range of options, including a beach volleyball court, running groups, yoga classes and much more. In addition, our company medical service and an experienced social counselling team are available to assist you on site
• Fair remuneration: Depending on your qualifications and assigned responsibilities, you will be classified according to pay group 13 (75%) of the TVöD-Bund. In addition to the basic salary, there is an additional year-end bonus under the collective pay agreement amounting to 75% of a monthly salary, as well as capital-forming benefits. All information about the TVöD-Bund collective agreement can be found on the BMI website (pay scale table on page 74 of the PDF download)
• Fixed-term: The position is initially for a fixed term of 3 years
• Support for international employees: Our International Advisory Service makes it easier for international employees to get started

You will obtain your PhD from Bonn University.
