Uli Zeitler, Steffen Wiedmann, HFML Nijmegen and Sergio Pezzini, Istituto Nanoscienze-CNR Pisa. The quantum Hall effect (QHE), a paradigmatic phenomenon of twodimensional (2D) electron systems in high magnetic fields, typically occurs only at very low temperatures of a few kelvin. [...]

Tino Gottschall, HLD Dresden. We are witnessing a great transition towards a society powered by renewable energies to meet the ever-stringent climate target. Hydrogen, as an energy carrier, will play a key role in building a climate-neutral society. Although liquid [...]

Alessandro Surrente, Wroclaw University of Science and Technology, Paulina Plochocka, Wroclaw University of Science and Technology and LNCMI Toulouse. The synthesis of colloidal nanocrystals with near-unity photoluminescence (PL) quantum yields has vastly extended the potential of metal-halide perovskites for solid-state [...]

Elena Blundo, Antonio Polimeni, Sapienza University of Rome, Adam Babiński, University of Warsaw, and Peter Christianen, HFML Nijmegen Strain plays an important role in two-dimensional (2D) semiconductors. Thanks to their all-surface nature, these 2D materials feature an extraordinary capability to [...]

J. Chang, Zürich University, M. Ichioka, Okayama University, D. Campbell, D. Le Boeuf, LNCMI Grenoble. In the physics of correlated electron systems, van Hove singularities play a key role. These are points in the band structure where the density of [...]

Denis Gorbunov, HLD Dresden. Optical excitations in solids require conservation of momentum and energy. This applies also to magnetic excitations, when a magnon with a given momentum and energy is created / annihilated by absorbing / emitting a photon. The [...]

Vincent Oliviero, David Vignolles, Cyril Proust, LNCMI Toulouse. In the last few years, high-magnetic-field studies have allowed great breakthroughs in the understanding of the physics of high-Tc cuprate superconductors. Here, we report the measurements of quantum oscillations and Hall effect [...]

Jan Wyzula, Milan Orlita, LNCMI-CNRS Grenoble and Mark O. Goerbig, LPS-CNRS Orsay Ever since the advent of graphene and topological materials, relativistic physics has become an integral part of condensed-matter sciences. While emergent, it is important to stress that this [...]

Peter Christianen, HFML Nijmegen. The development of pulsed, high-intensity terahertz free-electron lasers (FELs) has enabled the investigation of nonlinear phenomena in molecules and solids in the terahertz regime. To expand their potential, recently THz FELs were combined with high magnetic [...]

Yurii Skourski, HLD Dresden. A group of researchers from Korea, USA, and HLD have demonstrated that topological nodal-line degeneracy of spin-polarized bands in magnetic semiconductors can induce an extremely large angular dependence in the magnetotransport. A phenomenon that the researcher [...]
