Modeling of spin Hall induced domain wall dynamics in core-shell nanowires
Recent progress in domain wall nucleation and its control in nanostructures with tubular shape [see Figure 1] makes them fascinating objects for fundamental research as well as for data storage advanced technologies. In these systems the interplay between magnetization and 3D properties results in novel physical phenomena such as unconventional spin textures, additional energy terms […] >>

Modeling and design of hybrid semiconductor/magnetic circuits based on the interconversion between spin and charge currents and on the control of magnetic properties by electrical field
Spin electronics is a merging of microelectronics and magnetism which aims at taking advantage of the best of the two worlds. Magnetism is very appropriate for memory functions since it allows encoding information in a nonvolatile way via the direction of magnetization of magnetic nanostructures. Magnetic memory called MRAM (Magnetic Random Access Memories) are about […] >>

Coupling arrays of non-linear nano-oscillators: a theoretical and experimental study
Spin momentum transfer allows exploring and studying the non-linear magnetization oscillations in nano-sized magnetic structures and opens potential for novel applications as integrated microwave components. A defining feature of spintronic oscillators is their non-linear dependence of the precession frequency on the amplitude (non-isochronicity) that provides for additional rf functionalities and that modifies the response to […] >>

Determining Electron Wave Functions and Object Potentials in Transmission Electron Microscopy: improvement of algorithms
Up to now transmission electron microscopy (TEM) was more focused on producing images or diffraction patterns of objects. Of course, some pioneering techniques like holography or focal series or ptychography have tried to reconstruct the electron waves functions at the exit surface of the observed objects, but their results and applications were quite limited or, […] >>

Quantum computing and the orthogonality catastrophe
Quantum physics is evolving from a purely academic field towards building actual technologies with potential applications. Among those, the quantum computer is one of the most fascinating possibilities. Operating a quantum computer is however a race against time, as one needs to build up entanglement before decoherence sets in. In this project, we will be […] >>
