28/05/2020 — Science newsPreferential out-of-plane conduction and quasi-one-dimensional electronic states in layered 1T-TaS2

Our colleague Eduard Tutiš, in collaboration with scientists from Switzerland, Germany and Department of Physics of PMF in Zagreb, published paper in npj 2D materials and Applications. The paper provides the first experimental and theoretical insight into the state with electronic orbitals getting self-organized into metallic objects (the “Chains of Stars”) extending in direction perpendicular to layers.

21/02/2020 — Science newsUltrafast hot phonon dynamics in MgB2 driven by anisotropic electron-phonon coupling

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 E2g mode in MgB2 by using first-principle quantum-field theoretical approach.

 

06/02/2020 — Science newsBroken adiabaticity induced by Lifshitz transition in MoS2 and WS2 single layers

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.

25/12/2019 — Science newsEquilibrium shape of single-layer hexagonal boron nitride islands on iridium

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.

17/12/2019 — Science newsConvergence of Nonperturbative Approximations to the Renormalization Group

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.

21/11/2019 — Science newsTransverse Detection of DNA Using a MoS2 Nanopore

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.

20/10/2019 — Science newsTailoring thermal conduction in anatase TiO2

Our colleague Osor Slaven Barišić, in collaboration with scientists from the Physical Department of PMF in Zagreb and École Polytechnique Fédérale de Lausanne in Switzerland, has published a paper in prestigious journal Communications Physics. The authors investigated thermal conductivity in anatase TiOsingle-crystals and exploited the influence of nano-structuring effects on the heat transport properties.

22/02/2019 — Science newsCooling of atoms using an optical frequency comb

Our cold atomic gases research team, N. Šantić, D. Buhin, D. Kovačić, I. Krešić, D. Aumiler and T. Ban published their work in Scientific Reports where the cooling of the rubidium atoms has been studied by an unconventional method based on the use of femtosecond laser, which in the frequency domain acts as an optical frequency comb. This method could enable cooling of atoms with strong transitions in UV spectrum range which cannot be cooled by laser due to shortage of continuous-wave laser light sources in this spectral range.

05/02/2019 — Science newsUnusual behavior of cuprates explained by heterogeneous charge localization

Our colleague Petar Popčević, in collaboration with scientists from the Physical Department of PMF in Zagreb, Technical University of Vienna, Austria, and the University of Minnesota has published a paper in prestigious journal Science Advances. In this work a phenomenological model of high temperature superconductors based on copper oxides (cuprates) which describes and connects the most important features of these materials is proposed.

25/01/2019 — Science newsOrganic insulators and the Mott-Anderson localization

Our colleagues Matija Čulo, Tomislav Ivek, Silvia Tomić, and Bojana Hamzić have together with collaborators from Zagreb, Japan, USA and Germany published an article about the influence of disorder on magnetotransport properties of organic insulators with Mott-Anderson localization. The article is published in Physical Review B and picked by editor as a highlighted paper.
