Hubbard model and show that they can coexist, especially when superconductivity is not the
energetically dominant phase. Due to a breaking of the C 4 symmetry, the coexisting phase
inherently contains admixture of the s-wave pairing components. As a result, the
superconducting gap exhibits nonstandard features including changed nodal directions. Our
results also show that in the optimally doped regime the pure superconducting phase is …
