Títol: Designing Dynamics: From Chaos to Confinement in Stellarators
Resum: Stellarators aim to confine hot plasmas using carefully designed magnetic fields. Behind this engineering challenge lies a wealth of problems in dynamical systems involving Hamiltonian mechanics, chaos, resonances, and invariant tori. While invariant tori help keep plasma confined, carefully controlled chaotic transport can also be desirable. In this talk, I will describe how tools from dynamical systems can help us understand and design the magnetic fields in stellarators. I will present some of my work on chaos detection, integrability of magnetic fields, and guiding centre dynamics. As I do so, I will highlight several interesting problems from stellarator design that I think a dynamical systems approach may bring insight to.
