We develop the Gutzwiller approximation method to obtain the renormalized Hamiltonian of the SU(4) t-J model, with the corresponding renormalization factors. Subsequently, a mean-field theory is employed on the renormalized Hamiltonian of the model on the honeycomb lattice under the scenario of a cooperative condensation of carriers moving in the resonating valence bond state of flavors. In particular, we find the extended s-wave superconductivity is much more favorable than the d + id…
