Piotr Kapuściński and Marek Potemski, LNCMI Grenoble. Strong Coulomb correlations together with multi-valley electronic bands in the presence of spin-orbit interaction are at the heart of studies of the rich physics of excitons in semiconductor structures made of monolayers of [...]

Stanislaw Galeski, MPI CPfS Dresden and Sergei Zherlitsyn, HLD Dresden. The quantum Hall effect (QHE) is traditionally considered to be a purely two-dimensional (2D) phenomenon. Recently, however, a three-dimensional (3D) version of the QHE was reported in the Dirac semimetal [...]

Timo Neumann, Felix Deschler, TU Munich and Mateusz Dyksik, Paulina Plochocka, LNCMI Toulouse. Hybrid metal-halide perovskites offer the opportunity for a novel control of spins in a high-performance semiconductor due to their exceptional tolerance to structural defects and impurities, combined [...]

Igor Vinograd and Marc-Henri Julien, LNCMI Grenoble. The ubiquity of charge-density waves (CDW) in cuprate superconductors is now well established, but the mechanism responsible for their formation remains debated. The generic aspects of the microscopic structure of the CDW are [...]

Tatsuya Yanagisawa, Hokkaido University and Sergei Zherlitsyn, HLD Dresden. Researchers from Japan and the Czech Republic, together with scientists from the HLD, have succeeded in identifying that electric quadrupoles play an important role in the magnetic order of the honeycomb-layer [...]

Banan Kerdi, Mathieu Pierre, Michel Goiran, and Walter Escoffier, LNCMI Toulouse.  Transition-metal dichalcogenides (TMDCs) are two-dimensional layered materials showing intriguing electronic properties, especially when thinned down to a single layer. We studied WSe2 monolayers fabricated at LNCMI-Toulouse through transport measurements. [...]

Dmitri Yakovlev and Peter Christianen, HFML Nijmegen. For a few decades, colloidal semiconductor nanocrystals have been the focus of intensive research. Due to the continuous progress in technology, nanocrystals with different sizes, shapes, compositions, and surface properties have been synthesized. [...]

Sanu Mishra, Albin Demuer, Ilya Sheikin, LNCMI Grenoble, and Dai Aoki, Tohoku University. Strongly correlated electron systems, such as high-temperature superconductors, iron-based superconductors, and heavy-fermion compounds, are of high experimental and theoretical interest. In these materials, unconventional superconductivity is believed [...]

S. Galeski, J. Gooth, MPI CPfS and T. Förster, HLD Dresden. The quantum Hall effect is a prominent example of a quantum phenomenon that is of great importance for research in solid-state physics and the application of electronic devices. Since [...]
