Tunnel view of how electrons play

https://www.mpg.de/4345437/tunnel_view_electrons?page=3

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.

Telling mirror molecules apart

The enantiomers of a chiral compound can be distinguished via microwaves. This procedure was developed by a research team including Melanie Schnell of the Center for Free Electron Laser Science CFEL and the Max Planck Institute for Nuclear Physics, also holds promise for the development a technique to separate left- from right-handed variants of a molecule.

Konstruktiver Konflikt im Supraleiter

https://www.mpg.de/6000224/supraleitung_ladungsdichtewelle_elektron-phonon-kopplung

In den keramischen Hochtemperatur-Supraleitern Neodymbariumcuprat und Yttriumbariumcuprat (YBCO) konkurrieren Ladungsdichtewellen mit der Supraleitung, wodurch die Sprungtemperatur unkonventioneller Supraleiter gesenkt wird. Wie Forscher um B. Keimer der Abteilung Festkörperphysik am Max-Planck-Institut für Festkörperforschung vermuten, könnten Ladungsdichtewellen in einem Übergitter aus dem Cuprats YBCO und dem ferromagnetischen Lanthancalciummanganat (LCMO)auch die Ursache einer langreichweitigen Elektron-Phonon-Kopplung sein, was ein Beispiel für die Wechselwirkung zwischen magnetischen und supraleitenden Materialien und die grundlegende Erkenntnisse für die Kontrolle der Supraleitung durch Magnetismus in der Materialwissenschaft liefert.
Sobald sie jedoch die Sprungtemperatur bei minus 213 Grad Celsius erreichten, verschwanden
