Domain of Theory and Simulations
The research constitutes the core of a recently funded project focused on the simulation of plasma turbulence in the tokamak boundary, and involves the study of basic plasma physics phenomena at play in this region, the use and refinement of state-of-the-art simulation codes, and comparison with experimental data.
We seek candidates with a background in theoretical plasma physics, preferably with experience in plasma simulations, that have recently obtained a Ph.D. or are near graduation.

We are looking for a postdoc to carry out research on stellarator optimization with Dr. Joaquim Loizu and as a part of the Simons Collaboration on Hidden Symmetries and Fusion Energy. The main goal is to explore the possibility of finding stellarator configurations that are robust in the sense of magnetic field integrability, namely, those for which the equilibrium magnetic field preserves the volume of magnetic surfaces when it is subject to perturbations in, e.g., the plasma pressure, the plasma current, or the external field produced by coils or magnets. This would allow designing stellarators with much less restrictive tolerances and ensure that their operation guarantees equilibrium magnetic fields that have good magnetic surfaces within the plasma volume in which fusion is supposed to take place. This research will involve developing and exploiting both the SPEC code (which can describe 3D MHD equilibria with magnetic islands and chaos) and the SIMSOPT code (which is the flagship code of this collaboration and contains a suite of tools for stellarator optimization).
The position would start around September 2022. The candidate is required to have a PhD in plasma physics, computational physics, computational science, or applied mathematics, preferably with a strong background in plasma theory and in particular MHD. Experience with MHD equilibrium codes and/or numerical optimization is greatly valued but not required.
