Denis Arčon is a scientific advisor at the Jožef Stefan Institute (IJS) and a full professor of physics at the Faculty of Mathematics and Physics (FMF), University of Ljubljana (UL). At IJS, he serves as the head of the Solid State Physics Department and the head of the research program Physics of Quantum and Functional Materials. He is a member of the Scientific Council of IJS, a member of the General Council of the European Magnetism Association, and an editor of the Journal of Physics and Chemistry of Solids.
His primary research interest focuses on the physics of correlated systems, where strong electronic correlations lead to competition between high-temperature superconductivity and quantum antiferromagnetic states. In his research, he employs a variety of complementary experimental techniques, particularly magnetic resonance methods, including nuclear magnetic resonance (NMR), electron paramagnetic resonance (EPR), and muon spectroscopy. He also continuously incorporates new experimental methods into his research, such as magnetometry using NV centers on material surfaces.
