Abstract
The superconductivity and the competing orders in the doped Mott insulator on the Shastry-Sutherland lattice were studied. The doped Mott insulator on the Shastry-Sutherland lattice was considered via the t-J model. It was observed that the U(1) slave-boson mean-field theory revealed the strong competition between different broken symmetry states. It was found that in some ranges of doping, there exist superconducting phases with or without coexisting translational-symmetry-breaking orders such as the staggered flux or dimerization.
