Heavy fermions observed at atomic-layer interface for the first time

A team led by the University of Osaka has directly observed an unusual heavy-fermion state forming at the boundary between a one-atom-thick material and a metal. Such states are linked to exotic quantum phenomena, including unconventional superconductivity, and the finding opens new ways to design quantum materials through their interfaces.

• Heavy-fermion state seen at the interface of a one-atom-thick material and a metal
• The states are tied to unconventional superconductivity and exotic quantum effects
• The result enables designing quantum materials via their interfaces
• The research was led by a University of Osaka team
