The Paul Scherrer Institute PSI is the largest research institute for natural and engineering sciences within Switzerland. We perform cutting-edge research in the fields of future technologies, energy and climate, health innovation and fundamentals of nature. By performing fundamental and applied research, we work on sustainable solutions for major challenges facing society, science and economy. PSI is committed to the training of future generations. Therefore, about one quarter of our staff are post-docs, post-graduates or apprentices. Altogether, PSI employs 2300 people.
The Accelerator Simulation and Advanced Modeling Group is looking for a highly motivated and talented PhD Student to investigate the fundamental physics of Dense Coulomb Clouds (CCs). This project combines state-of-the-art numerical modelling with experimental validation at leading facilities like Argonne National Laboratory, SwissFEL and EuPRAXIA.
Your tasks
- Develop and implement advanced computational models to simulate the evolution of CCs, incorporating particle-to-particle interactions and collisional effects, spanning from the classical relativistic regime into quantum
- Analyse simulation results and experimental data to understand the impact of density perturbations, thermalisation, and entropy on beam properties
- Collaborate with a multidisciplinary team of researchers
Your profile
- Master degree in Physics, Mathematics, Computational Science and Engineering
- Strong computational skills including HPC, particle-in-cell methods
- Knowledge of Kokkos is and additional benefit
- Good knowledge of plasma and quantum physics incl. correlated systems
- Excellent analytical and problem-solving skills
- Ability to work independently and collaboratively in a team environment
- Strong communication and writing skills
We offer
Our institution is based on an interdisciplinary, innovative and dynamic collaboration. You will profit from a systematic training on the job, in addition to personal development possibilities and our pronounced vocational training culture. If you wish to optimally combine work and family life or other personal interests, we are able to support you with our modern employment conditions and the on-site infrastructure. ETH Zurich will be the PhD granting university.
