Valence bonds in random quantum magnets: theory and application to YbMgGaO4

Valence bonds in random quantum magnets: theory and application to YbMgGaO4

We analyze the effect of quenched disorder on spin-1/2 quantum magnets in which magnetic frustration promotes the formation of local singlets. Our results include a theory for 2D valence-bond solids subject to weak bond randomness, as well as extensions to stronger disorder regimes where we make co...
