Ultrafast magnetism studies the fastest dynamics in magnetic materials. The control of such dynamics is promising for a new generation of ultrafast information storage technologies based on magnetic materials. For this, it is imperative to develop analytical models and numerical techniques that both inform and explain experimental results. A new approach to model ultrafast magnetism interprets the dynamics in the context of fluid dynamics, so-called “spin hydrodynamics”.
The main goal of this project is to develop a spin hydrodynamic model to analytically and numerically study the ultrafast dynamics of magnetic materials. A secondary goal is to deepen the connection between magnetic and fluid dynamics with emphasis in dispersive hydrodynamics, rare events, and turbulence. The original research performed in this project will contribute to the development of ultrafast magnetic storage.
The successful candidate will have a solid background in applied mathematics or theoretical physics with strong analytical and programming skills. Introductory understanding of asymptotic methods, dispersion of waves, finite differences, solid-state physics, and quantum-mechanics is essential. Knowledge in magnetisation dynamics, electromagnetic waves, and fluid dynamics is desirable. Throughout the development of the project, the candidate is expected to interact with an international, multidisciplinary team of researchers and present research outcomes at national and international conferences in both poster and oral formats. The candidate will have access to experimental data taken at X-ray user facilities, e.g., EU-XFEL, in order to validate or improve the mathematical models. As such, the candidate will have the opportunity to process, analyse, and interpret high-quality experimental data.
The principal supervisor for this project is Dr Ezio Iacocca. The second supervisor will be Professor Gennady El.
