On 19th Sept. 2018, there was a racially motivated assault on a foreign PhD student in a tram of DVB. In an open letter, the PhD representatives from six Dresden research institutes clearly position themselves against any violence and oppression towards other people on the basis of their origin or culture. Furthermore, they emphasize the importance of an open and diverse society, especially for Dresden as a research location.
Hydrodynamic electron flow can only be observed in high-purity quantum materials. An international team of members from the IBM Research Laboratory Zurich, the University of Hamburg and the Max Planck Institute for Chemical Physics of Solids has now found signatures of electron hydrodynamics in the semimetal tungsten diphosphide. The results were published in the journal Nature Communications.[more]
In a recent study, scientists from the Max Planck Institute for Chemical Physics of Solids in Dresden have performed a comprehensive study of thermoelectric and thermomagnetic properties of polycrystalline Weyl semimetal NbP.
Die drei Dresdner Max-Planck-Institute – das MPI für die Chemische Physik fester Stoffe, das MPI für die Physik komplexer Systeme und das MPI für molekulare Zellbiologie und Genetik – organisieren eine gemeinsame Veranstaltung zum bundesweiten „Max-Planck-Tag“ in der Dresdner Innenstadt, genauer gesagt im Plenarsaal des Rathauses, um die Arbeit speziell ihrer Institute den Dresdnern und ihren Gästen zu präsentieren.[more]
Magneto-transport experiments of GdPtBi show anomalous Hall effect, chiral anomaly effect and non-zero Berry phase which establish the properties of Weyl physics. All these properties are independent of crystallographic directions. This study confirm that magnetism plays a major role in creating Weyl Fermions via exchange splitting of bands in GdPtBi.
Scientists at the Max Planck Institute Chemical Physics of Solids have written a review paper about magnetic topological materials in the family of Heusler compounds. The review explains the connection between topology, symmetry and magnetism at a level suitable for undergraduate students in physics, chemistry and materials science with a basic knowledge of condensed matter physics.
Scanning tunneling spectroscopy data on the archetypical heavy fermion metal YbRh2Si2 establish a hierarchy of energy scales, with the dominance of the lattice Kondo effect requiring temperatures well (about an order of magnitude) below the single-ion Kondo temperature of about 25 K. Only if the lattice Kondo correlations are sufficiently established, quantum critical fluctuations can evolve.
