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 [...]

J. F. Linnartz, A. Kool, S. Wiedmann, HFML Nijmegen and IMM Radboud. Quantum materials often exhibit remarkable sensitivity to subtle changes in their physical environment, a feature that can unlock new functionalities and drive innovative applications. One key phenomenon is [...]

Cyrille Train and Matteo Atzori, LNCMI-Grenoble. Magnetic materials are widely used for many technologies in areas such as energy, health, transportation, computation, and data storage. For the latter, the readout of the magnetic state of a medium is crucial. Optical [...]

Alex Eaton, University of Cambridge, UK and Yurii Skourski, HLD. Scientists from the UK, USA, Czech Republic, and Germany have studied the Fermi surface of the heavy-fermion superconductor UTe2. This material is of particular interest given its high likelihood of [...]

Tristan Thebault, William Knafo, LNCMI Toulouse, Daniel Braithwaite, Gérard Lapertot, Georg Knebel, CEA-Grenoble, and Dai Aoki, Tohoku University. The interplay between magnetism and unconventional superconductivity in UTe2 was extensively studied in the past few years. Multiple superconducting phases were found [...]

Y. Tokunaga, Japan Atomic Energy Agency, Tokai, Japan, M. Horvatić and Steffen Krämer, LNCMI Grenoble. The uranium-based superconductor UTe2 provides an attractive platform for studying the novel physics of spin-triplet and topological superconductivity in bulk materials. Resistivity measurements performed in 2019 [...]

Maurice Bal, HFML Nijmegen. Since its discovery in 1980 by von Klitzing et al., the quantum Hall effect (QHE) has been measured in many different 2D systems, mainly at cryogenic temperatures. Currently, graphene is the only material that displays the [...]

Z. Yang, Y. Kohama, ISSP, University of Tokyo, Japan and D. K. Maude, LNCMI Toulouse. We have investigated quantum oscillations in the electronic specific heat, Cel, in natural graphite. The crossing of a single spin Landau level at the Fermi [...]
