Triplet <i>p</i> + <i>ip</i> pairing correlations in the doped Kane-Mele-Hubbard model: A quantum Monte Carlo study

By using the constrained-phase quantum Monte Carlo method, we performed a systematic study of the pairing correlations in the ground state of the doped Kane-Mele-Hubbard model on a honeycomb lattice. We find that pairing correlations with $d+id$ symmetry dominate close to half filling, but pairing correlations with $p+ip$ symmetry dominate …
