Quantum criticality with emergent symmetry in the extended Shastry-Sutherland model

Wen-Yuan Liu, Xiao-Tian Zhang, Zhe Wang +3

Motivated by the novel phenomena observed in the layered material $\mathrm{SrC}{\mathrm{u}}_2(\mathrm{B}{\mathrm{O}}_3{)}_2$, the Shastry-Sutherland model (SSM) has been extensively studied as the minimal model for $\r…
