Deconfined gapless phases and criticalities in the Shastry-Sutherland antiferromagnet

Author(s): Lv-Cheng Chen and Zheng-Xin LiuAntiferromagnets on the Shastry-Sutherland lattice have attracted lots of research interest due to the possible existence of deconfined criticality. In the present work, we study the {J}_{1}\text{−}{J}_{2}\text{−}{J}_{r} model using variational Monte Carlo…
