Doctoral researcher positions in Quantum Information Theory

About us

The University of Luxembourg is an international research university with a distinctly multilingual and interdisciplinary character.

The Faculty of Science, Technology and Medicine (FSTM) at the University of Luxembourg contributes multidisciplinary expertise in the fields of Mathematics, Physics, Engineering, Computer Science, Life Sciences and Medicine.
Through its dual mission of teaching and research, the FSTM seeks to generate and disseminate knowledge and train new generations of responsible citizens in order to better understand, explain and advance society and environment we live in.

Your role

The successful candidates will work in the Nanomagnetism group led by Prof. Andreas Michels at the University of Luxembourg:

• Explore the relationship between intrinsic and collective magnetic properties in ordered and disordered nanoparticle assemblies, addressing both their equilibrium and dynamic behavior, with a focus on their representation in the SANS cross section and correlation function

• Study static spin structures and compute the dynamic (time-dependent) magnetization response, where the intermediate scattering function serves as the key neutron scattering observable

• Contribute to establishing a solid foundation for future studies on the coupling between thermal transport and magnetization dynamics in nanostructures, as well as on the impact of magnetism on the electrical, thermal, and magnetooptical properties of arrays of nanomagnets deposited, for example, on metallic or semiconducting substrates

Research on magnetic nanoparticles and nanostructures is largely motivated by their potential and existing applications in medicine, biology, chemistry, and nanotechnology. A key question in this field is whether assembling individual nanoparticles into macroscopic systems, e.g. ordered arrays of nanoparticles, preserves their unique nanoscale properties. Addressing this challenge requires a thorough understanding of the interplay between the intrinsic properties of nanoparticles such as size, shape, and defect structure and their interactions within complex assemblies. From a fundamental standpoint, advancing our knowledge of nanoscale behavior necessitates sophisticated tools to probe, measure, and model these systems. Utilizing polarized magnetic neutron scattering, particularly small-angle neutron scattering (SANS), we have recently developed a theoretical framework that combines analytical and numerical approaches to quantitatively investigate the spin structures and surface anisotropy of nanoparticles. SANS is particularly sensitive to mesoscale variations (approximately 1-1000 nm) in the magnitude and orientation of the static magnetization vector field. These efforts, which form the foundation of the present project, have significantly advanced our understanding of the magnetic structures of nanoparticles and their distinctive signatures in experimental neutron scattering data.

Your profile

We are looking for a motivated researcher at the PhD student level. This theory project will comprise both analytical calculations as well as numerical simulations of classical spin systems. The PhD candidate should have a MS degree in physics or materials science, ideally with a specialization in condensed-matter physics and magnetism.

The project will be carried out in the group of Professor Andreas Michels at the University of Luxembourg in collaboration with the group of Professor Hamid Kachkachi at the University of Perpignan. The position includes travel funds for visiting schools and conferences, and possible extended research stays abroad.
