Quantum entanglement of XY-type spin dimers in Shastry-Sutherland lattice

Qianli Ma, Brianna R. Billingsley, Madalynn Marshall +8

We report a comprehensive study on the origin of the enigmatic disordered ground state within the Shastry-Sutherland lattice, BaCe${}_2$ZnS${}_5$, at low temperatures. The magnetizatio…
