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 [...]

Mateusz Dyksik, Wroclaw University of Science and Technology, Poland and Paulina Plochocka, LNCMI Toulouse. Optically inactive dark exciton states play an important role in light-emission processes in semiconductors because they provide an efficient nonradiative recombination channel. Understanding the exciton fine [...]

Jasper Linnartz and Steffen Wiedmann, HFML Nijmegen. A team of researchers from HFML-FELIX, Aarhus University, and the University of Bristol has investigated the high-field electronic transport properties of the semimetal WTe2. In quantum-oscillations measurements, they revealed peculiar magnetic-breakdown trajectories of [...]
