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.

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.
