Atomic spin-chain realization of a model for quantum criticality
NATURE PHYSICS(2016)
Abstract
Magnetic adatoms offer an appealing platform for building idealized spin models, but achieving sufficient control to do so is challenging. Now, arrays of Co atoms evaporated on a Cu 2 N/Cu(100) surface are shown to behave like a spin-1/2 XXZ Heisenberg chain.
