Abstract
Detecting signatures of many-body entanglement in frustrated magnetic systems remains a grand challenge in condensed matter. In this work, the authors show that this problem can be made more tractable by looking at the evolution of dilute magnetic systems to fully packed frustrated magnets. They study the system NaLu${}_{1\ensuremath{-}x}$Yb${}_{x}$Se${}_{2}$ as a model example, showing evidence that single defects evolve into entangled dimers, which in turn evolve into entangled multimers as $x$ approaches unity.
