Quantum engineered Kondo lattices.

ABSTRACT: Atomic manipulation techniques have provided a bottom-up approach to investigating the unconventional properties and complex phases of strongly correlated electron materials. By engineering artificial systems containing tens to thousands of atoms with tailored electronic or magnetic properties, it has become possible to explore how quantum many-body effects emerge as the size of a system is increased from the nanoscale to the mesoscale. Here we investigate both theoretically and experimentally the quantum engineering of nanoscale Kondo lattices - Kondo droplets - exemplifying nanoscopic replicas of heavy-fermion materials. We demonstrate that by changing a droplet's real-space geometry, we can not only create coherently coupled Kondo droplets whose properties asymptotically approach those
