Abdou Hassanien from Jozef Stefan Institute in collaboration with Biao Zhou and Akiko Kobayashi from Nihon University, Tokyo, Japan, have published article in Journal of Advanced Electronic Material titled Spontaneous Antiferromagnetic Ordering in a Single Layer of (BETS)2GaCl4 Organic Superconductor. The fabrication of such well-defined and atomically clean interfaces between materials of different orders are of fundamental interest to engineer novel functionalities and to study emergent phenomena in condensed matter physics. The paper illustrates the interplay between electronic orders of hybrid mix of nested antiferromagnetic molecular chains and superconducting molecular stripes at the single layer limit. Results of low temperature scanning tunneling microscopy and spectroscopy have shown that low level vibronic and magnetic excitations that dominate the higher temperature phase are absent below Tc which point to their cooperative existence and possible renormalization to mediate superconductivity in such d-wave superconductors.
Guilhem Poy from Faculty of Mathematics and Physics at University of Ljubljana and Slobodan Žumer from Jozef Stefan Institute in collaboration with the group of Ivan Smalyukh from University of Colorado in Boulder in Physical Review X published the paper that Control of Light by Topological Solitons in Soft Chiral Birefringent Media, was highlighted in APS Physics Focus by the editorial article “Liquid-Crystal Vortices Focus Light”. Topological solitons appearing in different areas of physics are fascinating localized perturbations of ordering fields enjoying topological protection. The authors demonstrate refraction, reflection, and lensing of weak laser beams by various topological solitons in frustrated chiral nematics and show how interactions of light with such topological solitons are well described using a generalized Snell’s law and ray-tracing models. These may lead to new means for controlling flow of light for use in optics and photonics.
Prof. dr. Sašo Šturm, Head of Department for Nanostructured Materials, was elected as a member in Executive Board of European Microscopy Society (EMS). The aims of EMS are to promote the use and the quality of advanced microscopy in all its aspects in Europe, with particular reference to developments in instrumentation, methodology and novel applications of all types of microscopy. Prof. dr. Sašo Šturm was proposed by the Slovene Society for Microscopy (SDM) Executive Board and thus the Slovenian representative in the EMS Executive Board was elected for the first time. Prof. dr. Sašo Šturm will promote the use and development of advanced microscopy techniques across different disciplines, crossing the boundaries between academia and industry. In these sense he will propose to intensify the scientific and/or technical contributions from the industrial environments, focusing on end‐users and not only on the producers, at the international and national conferences related to microscopy.
Tome Eftimov, Gorjan Popovski, Matej Petković, Barbara Koroušić Seljak and Dragi Kocev from E7 and E8 have performed a computational analysis of online recipes and reported their findings in the paper COVID-19 pandemic changes the food consumption patterns. They discovered that the relative increase in frequency was most notable for Pulses/plants producing pulses (dry beans, peas, lentils, beans, vetches, and lupins) - 300%, Pancake/Tortilla - 280 %, Soups 180%, and Pastry, Fruit containing stone, Cake and Beef - 100%. They observed reduced relative frequencies on the tags Order Perciformes (fish) (50% reduction), Corn/cereals/grain (40%), Wine-making (30%), and with 10% Citrus fruit, Pork, Water, and Seafood. These results can be used as indicators for the potential post-lockdown health implications and increased incidences of some diseases, agricultural practices as well as the food supply chain and logistics in such events.
