An international research team has discovered that topological electronic states are present in nearly every known material for every electron in the crystal configuration. Appearing this week in Science, the team’s discovery of ubiquitous band topology has motivated re-examining previous experimental data for overlooked topological features, and suggests that the century-old field of band theory should be restructured, with topology joining chemistry and geometry on equal footing.
 

The study of ultra-pure materials still has many ways to surprise and delight! For delafossite metals it was shown that wires sculpted from the same single crystal have very different resistivities depending on the angle at which they are cut.  From the fundamental physics point of view, the laws of bulk resistivity are being broken.
 

We are happy to announce that Professor Joshua Goldberger from The Ohio State University in the United States has been awarded a Friedrich Wilhelm Bessel fellowship sponsored by the Humboldt foundation. This prestigious fellowship entitles him to spend a sabbatical in Germany, most of the time at our institute in the department of Solid State Chemistry.
