Stanislaw Galeski, HLD and HFML-FELIX. The ability to transport heat is one of the most fundamental properties of matter, crucial for engineering applications. In most materials, at room temperature transport is well understood. Things, however, are not as straightforward under [...]

Zhuo Yang and Yoshimitsu Kohama, ISSP at University of Tokyo, Japan, Duncan K. Maude, LNCMI-Toulouse, Christophe Marcenat, CEA, IRIG, and PHELIQS, Grenoble. In the mixed-valence compound YbB12, thermal-conductivity measurements at low temperatures reveal highly mobile excitations that carry heat like [...]

Florian Le Mardelé and Milan Orlita, LNCMI-Grenoble. Alloying stands out as a pivotal technological method employed across various compounds, be they metallic, magnetic, or semiconducting, serving to fine-tune their properties to meet specific requirements. Ternary semiconductors represent a prominent example [...]

Raj Pandya, University of Warwick, UK, Chris Howard, University College London, UK, Peter Christianen, HFML-FELIX Nijmegen. For the first time, researchers have demonstrated that phosphorene nanoribbons – thin pieces of black phosphorus, only a few nanometers wide (figure 1, bottom) [...]

Toni Helm, HLD. Superhydrides are metallic hydride compounds that exhibit superconductivity (SC) under mega-bar pressure at extraordinarily high temperatures. The observation of superconducting critical temperatures, Tc, as high as 250 K has revived scientists' dream of room-temperature superconductivity. While current [...]

Jérôme Long, ICGM, Montpellier, France, Luís D. Carlos, University of Aveiro, Portugal, Paulina Plochocka, LNCMI Toulouse. Luminescence thermometry has gained significant attention as a versatile and non-invasive tool for remote temperature measurements in diverse fields, including nanomedicine, microelectronics, catalysis, and [...]

Badih Assaf, University of Notre Dame, USA, Milan Orlita, LNCMI-Grenoble. Magnetic circular dichroism (MCD) is a widely known phenomenon with a long history in physics that dates back to the original experiments carried out by Faraday, dealing with the interaction [...]

Km Rubi, NHMFL, Los Alamos, USA, Walter Escoffier, LNCMI Toulouse, Uli Zeitler, HFML-FELIX Nijmegen. In the last two decades, two-dimensional electron systems (2DES) have been observed at the surfaces and interfaces of severalperovskite transition-metal oxides, so-called complex oxides. In particular, [...]

Sergei Zvyagin, HLD. The importance of attractive forces, stabilizing multi-particle bound states in condensed matter is generally accepted. By contrast, multiparticle bound states stabilized by means of repulsive forces were long thought to be only theoretical constructions, due to the [...]

V. Oliviero, D. Vignolles, C. Proust, LNCMI Toulouse, W. A. Atkinson, Trent University, Canada. The ubiquity of the interplay between antiferromagnetic (AFM) order, charge density waves (CDWs), and superconductivity is a general feature of hole-doped cuprates. The role of AFM [...]
