Entanglement-induced Kondo screening in atomic spin chains

Understand

Quantum entanglement permeates the complex ground states of correlated electron materials defying single-particle descriptions.

• Coupled magnetic atoms have potential as model systems for entanglement in condensed matter giving the opportunity to create artificial many-body states which can be controlled by tuning the underlying interactions.
• They provide an avenue to unravel the complexities of correlated-electron materials.
• Here we use low temperature scanning tunnelling microscopy (STM) and atomic manipulation to tune entanglement in chains of magnetic atoms.
