Tunnel view of how electrons play

https://www.mpg.de/4345437/tunnel_view_electrons?page=1

Electrons behave like football teams: the match becomes interesting when the teamwork is as good as that conjured up by the players of FC Barcelona. Electrons which interact strongly with each other give rise to superconductivity, the lossless transport of current, for example. A team headed by researchers at the Max Planck Institute for Chemical Physics of Solids in Dresden is now taking a completely new look at the teamwork between electrons. They have used a scanning tunnelling microscope to investigate the Kondo effect in the metal ytterbium rhodium silicide YbRh2Si2, which contains unpaired electrons and thus magnetic moments. At low temperatures, the strong interactions between the electrons completely shield the magnetic moments from each other. The Dresden-based physicists have now observed how this shielding is created. Their work also shows how well electronic processes in solids can be investigated with scanning tunnelling microscopes.

Tunneln nahe der Lichtgeschwindigkeit

Das Bild des quantenmechanischen Tunneleffektes bleibt auch bei einer relativistischen Betrachtung, wenn ein Elektron durch einen intensiven Laser fast bis auf Lichtgeschwindigkeit beschleunigt wird, gültig. Wie Forscher um C. Keitel vom Max-Planck-Institut für Kernphysik berechnet haben, lässt sich dabei auch die Eisenbud-Wigner-Smith-Zeit – die Zeit, die das Elektron zum Tunneln braucht – ermitteln.

Solidarity in the stadium

https://www.mpg.de/18618260/solidarity-in-the-stadium?c=12643140

In large swathes of Germany’s industrial Ruhr Valley region, coal mining is a thing of the past as is true in other European coalfields. But people in the affected regions continue to be hard hit by the associated job losses, as jobs not only secured their livelihoods, but also created a sense of community. At the Max Planck Institute for Human Development Julia Wambach is looking into what replaced worker solidarity and has come across two committed football clubs: FC Schalke 04 and the French club RC Lens.
The players‘ tunnel in the new arena is modelled after a coal seam and the players
