Abstract
A two-dimensional electron system with both spin and orbital degrees of freedom is investigated with the slave-boson mean-field approaches. By introducing the resonating-valence-bond order parameters, we show that the system may exhibit superconductivity after the slave bosons “condensation.” It is found that the electron pairs are spin singlets and orbital singlets but the system shows p-wave superconductivity with the symmetry of kx±iky.
