Unconventional superconductivity found in kagome metal

Posted by in categories: engineering, quantum physics

Physicists using advanced muon spin spectroscopy at Paul Scherrer Institute PSI found the missing link between their recent breakthrough in a kagome metal and unconventional superconductivity. The team uncovered an unconventional superconductivity that can be tuned with pressure, giving exciting potential for engineering quantum materials.

A year ago, a group of physicists led by PSI detected evidence of an unusual collective electron behavior in a kagome metal, known as time-reversal symmetry-breaking charge order—a discovery that was published in Nature.

Although this type of behavior can hint towards the highly desirable trait of , actual evidence that the material exhibited unconventional superconductivity was lacking. Now, in a new study published in Nature Communications, the team have provided key evidence to make the link between the unusual charge order they observed and unconventional superconductivity.
