Superconductivity: When soap bubbles turn to soup

5 Oct 2021

With the help of high-resolution microscopy, Munich based scientists successfully observed the transformation of a metal of magnetic polarons into a normal Fermi liquid.

Magnetic polarons are prime suspects to be responsible for the emergence of high-temperature superconductivity in copper-oxide ceramics. Magnetic polarons are quasiparticles that you can imagine as soap bubbles floating around in a room. To date, the interplay of these bubbles remains poorly understood.
