Our colleague Dino Novko, in collaboration with scientists from Humboldt-University in Germany and Istituto di Struttura della Materia in Italy, has published a paper in prestigious journal Physical Review Letters. The authors investigate the unique hot phonon dynamics of E_2g mode in MgB₂ by using first-principle quantum-field theoretical approach.

Dino Novko, research associate at the Institute of Physics, published a paper in the prestigious journal Communications Physics, where he proved that the adiabatic Born-Oppenheimer approximation is not valid in transition metal dichalcogenides and that a strong nonadiabatic phonon renormalization is triggered at the Lifshitz transition.

Just before Christmas we recieved great news from our colleague Marin Petrović who, in collaboration with colleagues from the University of Duisburg-Essen, came to new findings important for understanding of synthesis of single-layer hexagonal boron nitride. Research results have been published in Scientific Reports, where it is shown how the morphology of the substrate which is used in the synthesis determines the shape of the growing domains of the hexagonal boron nitride.

Ivan Balog, together with a collaboration of scientists from Sorbonne Université, Visage Technologies AB, CEA Saclay and the University of Montevideo, has published an article in the prestigious journal Physical Review Letters. Authors have studied the convergence properties of the derivative expansion, an approximation which is often used for calculating the long wavelength properties in statistical physics, condensed matter and high energy physics.

Our colleague Damir Altus, together with Institute’s alumni M. Lihter and S. Marion, who currently work in the group of prof. A. Rađenović at the École Polytechnique Fédérale de Lausanne, published a paper in prestigious journal Nano Letters about DNA detection using a MoS₂ nanopore. DNA molecules are sensed by correlated signals from the ionic current through the nanopore and the transverse current through the nanoribbon. The resulting signal suggests a field-effect sensing scheme where the charge of the molecule is directly sensed by the nanoribbon.
