Milan Orlita, LNCMI-Grenoble. When a magnetic field is applied to a solid, the continuous density of electronic states transforms into a set of discrete energy levels, known as Landau levels. Electrons excited in such a ladder may recombine, with [...]

Denis Gorbunov, HLD Dresden. Intermetallic compounds based on 3d and 4f elements combine high magnetic ordering temperatures, typical of 3d metals, and the large magnetic anisotropy of the magnetic rare-earths elements. The application of external magnetic fields tunes the [...]

William Knafo, Marc Nardone (LNCMI Toulouse), Sanu Mishra (LNCMI Grenoble) and Georg Knebel (CEA-Grenoble). Following the recent discovery of superconductivity in the heavy-fermion paramagnet UTe2, which is suspected to lie on the verge of ferromagnetism [S. Ran et al., [...]

Nigel Hussey, HFML Nijmegen. It is not only elemental or ordinary metals that superconduct. Today, scientists are also fascinated by strange metals that undergo phase transitions (e.g. to a magnetic state) before superconductivity sets in. If they find the [...]

Steffen Wiedmann, HFML Nijmegen. In 2017 and 2018, two PhD students from Brazil came to Nijmegen to do a part of their post-graduate program at the EMFL facility in Nijmegen. They obtained a one-year PhD fellowship from the Federal Agency [...]

Sergei Zvyagin, HLD Dresden. Spin-1/2 triangular-lattice Heisenberg antiferromagnets represent one of the most important classes of frustrated quantum magnets, demonstrating a complex interplay between geometrical frustration, quantum fluctuations, and magnetic order. In spite of their simple magnetic structures (Figure, [...]

Yo Tokunaga, JAEA Tokai, Nicolas Bruyant, LNCMI-Toulouse, and Ilya Sheikin, LNCMI-Grenoble. Heavy-fermion materials exhibit a diverse range of fascinating phenomena including quantum phase transition (QPTs), non-Fermiliquid behavior, and novel states of matter such as unconventional superconductivity. The application of [...]

Sergio Pezzini, Steffen Wiedmann, Uli Zeitler, HFML Nijmegen. Two-dimensional layers of graphene and hexagonal boron nitride (hBN) both have a honeycomb atomic structure, with a slight lattice mismatch of 1.8 %. When placing graphene on top of hBN one [...]

Leah Weiss, Sam Bayliss, University of Cambridge and Paulina Plochochka, LNCMI-Toulouse.  Intermolecular coupling plays a key role in charge transport and excited-state dynamics in organic systems. A key example of the influence of intermolecular interactions is the process of [...]

Zhe Wang, HZDR Dresden and A. Loidl, University of Augsburg.  In his seminal work entitled “Eigenwerte und Eigenfunktionen der linearen Atomkette” (eigenvalues and eigenfunctions of a linear chain of atoms), published in 1931 in “Zeitschrift für Physik”, Hans Bethe [...]
