Model-Based Simulation of Dynamics in Ferromagnetic Nanostructures
Supervisors: Prof. Ralf Röhlsberger (DESY Hamburg), Dr. Guido Meier (MPSD), Jun.-Prof. Christina Brandt (UHH)

After completing her Bachelor studies in Physics in 2017 from St. Stephen's college, New Delhi, Ankita moved to Germany to do her Master's degree at the Institute for Theoretical Physics, University of Cologne. Her Master thesis was completed in January 2020. It involved modelling a Chern topological insulator in the presence of different disorder profiles and using Transfer Matrix computations to deduce its phase diagrams.
In her PhD project within DASHH, the project team joins forces in the fields of high-frequency magnetic dynamics (Dr.. Meier), model-based simulation and identification of magnetic spin structures (Jun.-Prof. Brandt) and synchrotron radiation methods for determination of static and dynamic magnetic structures (Prof. Röhlsberger), in order to explore new regimes in the field of Spintronics and ultrafast THz dynamics in finite spin systems. They also want to go into “cavitronics” with various materials including anti-ferromagnets. The exact tailoring of magnetic spin systems in thin films and nanostructures plays an important role for designing micromagnetic devices. Spin waves in these micromagnets are promising candidates as a building block for future logic or signal processing devices. Therefore, fundamental as well as application-directed research in this field is needed to achieve significant advances in high speed information processing.
