"Breakthrough: German Scientists Solve Key Condensed Matter Physics Puzzle"

A team of physicists at the University of Cologne has successfully observed the Kondo effect in an artificial atom using a scanning tunneling microscope, marking a significant breakthrough in condensed matter physics. Their innovative approach allowed them to directly observe the Kondo effect in a one-dimensional wire floating above a metallic sheet of graphene, validating theoretical predictions and opening new possibilities for exploring exotic states of matter.
