Superconductivity in a two-dimensional hole-doped spin-orbital system
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 (RVB) 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 k_x± ik_y.
