Nature Physics published an article entitled Observation of two types of fractional excitation in the Kitaev honeycomb magnet by members of the Condensed Matter Physics Department at Jožef Stefan Institute, Nejc Janša, Andrej Zorko, Matjaž Gomilšek, Matej Pregelj and Martin Klanjšek, and colleagues from Switzerland. The article describes the first clear confirmation of the existence of two types of anyonic quasiparticle in a layered crystal α-RuCl3, which is known as the best realization of the Kitaev honeycomb lattice. A decade old famous Kitaev prediction spurred numerous experimental efforts to confirm the existence of anyons. The discovery is important also as the braiding operations with anyons offer one of the most promising platforms for topological quantum computing.


A review article Anisotropic magnetic nanoparticles: A review of their properties, synthesis and potential applications has been published in the journal Materials Science (impact factor 31.140), after an invitation from the Editor, by Prof. Dr. Darja Lisjak (Department for Materials Synthesis) and Dr. Alenka Mertelj (Department of Complex Matter). The research on magnetic nanoparticles has been increasing in the last two decades or so due to their interesting properties and a wide range of applications in techniques, ecology and bio-medicine. The authors focused on the anisotropic magnetic nanoparticles that, in addition to their nano dimensions, show scientifically relevant and applicable properties due to their anisotropic shapes.


The journal Nature Communication has published the scientific work of Prof. Dr. Uroš Cvelbar and his colleagues from Korean university KAIST,The creation of electric wind due to the electrohydrodynamic force, where they unlocked the secret of electric wind origin. They report on direct evidence that the wind is generated by electrohydrodynamic force, which is caused by coupling of charged particles with neutrals. Coupling between these particles has a long history and is a popular scientific subject since it is supposed to be one of the basic mechanisms of natural phenomena including convection of ions and neutrals in planetary atmospheres and movement of neutrals in electric discharges. The direct evidence for this phenomena will probably improve fundamental knowledge on plasma, ranging from plasma processing, fusion, astrophysics to space propulsion.


One of the very first attempts to understand the charge dynamics in mixed-valence systems dates back to 1939 when Evert Verwey, a Dutch chemist, observed a sudden jump in resistivity near -150 °C in magnetite. In the journal Science Advances now a research team of scientists from Germany and Slovenia reports a Verwey-type transition in a completely different class of mixed-valence compounds, which is composed of negatively charged dioxygen molecules. The compound Cs4O6 undergoes a phase transition from a state with indistinguishable molecular O2x- entities to a state with well-defined superoxide O2- and peroxide O22-anions. The breakthrough of the present study is the observation of such charge ordering in a simple crystal structure where novel physical phenomena is expected to emerge from intertwining of degrees of freedom pertinent to electronically active oxygen molecular units.
