A team at the University of Cologne has successfully observed the elusive Kondo effect in an artificial atom, employing a novel approach with a scanning tunneling microscope. This significant advancement in condensed matter physics, validating theoretical predictions, opens new avenues for exploring exotic states of matter.
A team of physicists at the University of Cologne has solved a long-standing problem of condensed matter physics: they have directly observed the Kondo effect (the re-grouping of electrons in a metal caused by magnetic impurities) visible in a single artificial DOI: 10.1038/s41567-023-02250-w
