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. Understanding their optical, electrical, and chemical properties has led to [...]

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 to emerge near a quantum critical point. In addition, some [...]

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 1990, it defines the standard used in resistance calibrations. It [...]

Nigel Hussey, HFML and Anthony Carrington, University of Bristol. Researchers from the UK and Japan, together with scientists from three of the EMFL laboratories, have uncovered a striking crossover in the Hall resistivity across the so-called strange-metal phase of overdoped cuprate superconductors [1]. The work builds on a seminal work [...]

Sanu Mishra and Ilya Sheikin, LNCMI Grenoble, Tobias Förster, HLD Dresden, and Alix McCollam, HFML Nijmegen. Rare-earth-based materials are now widely recognized as an ideal playground for exploration of the fascinating physics that develops around a quantum critical point (QCP). In Ce-based compounds, such a QCP typically separates an antiferromagnetic [...]
