    • where a doped Kitaev-Heisenberg model is studied using the SU(2) slave boson representation. You also find a p-wave spin-triplet state; however, their order parameter breaks time-reversal symmetry in contrast to our result. While we found that the time-reversal violating state is slightly higher in energy, it remains to be clarified whether correlation effects beyond the present level of approximations would tip a balance between the two solutions.
