معرفی
Goran Jan Nilsen is an Associate Professor in Materials Physics at the Department of Mathematics and Physics, Faculty of Science and Technology, University of Stavanger (UIS). His research is focused on quantum magnetic materials and experimental condensed matter physics, particularly using neutron scattering techniques to probe spin dynamics and crystal field effects.
His research interests lie at the intersection of quantum magnetism and materials physics. He investigates strongly correlated electron systems, including spin ice phases, low-dimensional quantum magnets, and honeycomb lattice materials exhibiting Kitaev-type interactions. His work often involves the synthesis and characterization of novel magnetic compounds such as β-VOSO4, RuP3SiO11, and NdCo5, with a strong emphasis on understanding emergent phenomena arising from magnetic frustration and spin-orbit coupling.
The recent publications indicate a consistent focus on using neutron scattering methodologies—especially inelastic and polarized neutron techniques—to explore fundamental magnetic behavior in transition metal and rare-earth-based materials. Themes across these works include quantum spin liquids, one-dimensional magnetism, crystal field spectroscopy, and the role of extended superexchange in driving exotic magnetic interactions.
Scientific Contributions:
- Investigation of Kitaev interactions in jeff = 1/2 systems
- Dynamics of antiferromagnetic spin ice in pyrochlore spinels
- Crystal field excitations in rare-earth intermetallics via neutron scattering
- Development of neutron polarization analysis methods
Nilsen actively collaborates with international research teams and institutions, contributing to high-impact studies in top-tier physics journals.
