Unconventional superconducting states on doped Shastry-Sutherland lattice

Huai-Xiang Huang, Yan Chen, Guo-Hong Yang

By using a renormalized mean-field theory, we investigate the phase diagram of $t$-$t^{\prime }$-$J$-$J^{\prime }$ model on two dimensional Shastry-Sutherland lattice which are topologically equival…
