Assuming that the insulating phase is an anti-ferromagnetic insulator, we show that fluctuations of the anti-ferromagnetic order in the conducting phase can mediate superconducting pairing. Using a self-consistent mean-field analysis, we find that the pairing wave function has a chiral d-wave symmetry. Consistent with this observation, we show explicitly the existence of chiral Majoran","authors_text":"Chuan Chen, Evan Laksono, Giovanni Vignale, Jia Ning Leaw, Shaffique Adam, Vitor M.
