Robert A. Jagt, Bartomeu Monserrat, Judith L. MacManus-Driscoll, Robert L. Z. Hoye, University of Cambridge, UK and Paulina Płochocka, LNCMI Toulouse. Modern advances in x-ray imaging have greatly improved the quality of medical care. The ability to detect low doses [...]

Sergei Zherlitsyn, HLD Dresden. By investigating the Shastry-Sutherland compound SrCu2(BO3)2 up to the saturation magnetic field of 140 T and beyond, researchers from Japan, the Netherlands, and Switzerland together with scientists from the HLD have succeeded in identifying several spin-supersolid [...]

Oleksandr Zheliuk, HFML Nijmegen. Scientists from the University of Groningen, together with colleagues from HFML Nijmegen, the University of Twente, and the Harbin Institute of Technology (China), have discovered the existence of a superconducting state that was first predicted in [...]

Hannes Kühne, HLD Dresden. Two-dimensional (2D) spin systems with an XY anisotropy are known to undergo a Berezinskii-Kosterlitz-Thouless (BKT) phase transition at a finite temperature TBKT, which marks the binding of topological defects in vortex-antivortex pairs. So far, experimental efforts [...]

Ramakanta Chapai, J. F. Mitchell and Ulrich Welp, Argonne National Laboratory, Vincent Oliviero, Maxime Leroux, LNCMI Toulouse. The recently discovered-kagome lattice compounds AV3Sb5 (A = K, Rb, Cs) show a fascinating interplay of superconductivity, charge density wave (CDW) order, and [...]

Matija Čulo, Institute of Physics, Zagreb, Croatia and Nigel Hussey, HFML and University of Bristol, UK. High-temperature superconductivity is one of the biggest unsolved problems in condensed-matter physics, due to its unconventional superconducting (SC) pairing mechanism, which goes beyond the [...]

Jan Wyzula and Milan Orlita, University of Fribourg and LNCMI Grenoble. Magnons, or quantized spin waves, are collective magnetic excitations in solids. These boson-like quasiparticles disperse with lattice momentum k, carry a fixed energy, and possess an integer spin or [...]

Sergei Zvyagin, HLD Dresden. Antiferromagnetic materials with spin 1/2 and triangular-lattice structures are in the focus of modern quantum physics, in particular, in connection with Anderson’s idea of “resonating valence bond” states in frustrated spin systems. He proposed that the [...]

Amirreza Ataei and Louis Taillefer, Université de Sherbrooke, Canada, Cyril Proust and David Vignolles, LNCMI-Toulouse. In certain materials called “strange metals”, the electrical resistivity follows a perfectly linear temperature dependence at low temperature, in contrast to the standard quadratic dependence [...]

Amit Pawbake and Clément Faugeras, LNCMI Grenoble. Spin waves (magnons) in magnetically ordered solids – ferromagnets or antiferromagnets – are collective excitations of an ensemble of spins. They propagate in the solid and do couple to phonons of the host [...]
