Chiral Superconductivity from Spin Polarized Chern Band in Twisted MoTe_{2}

Superconductivity has been observed in twisted MoTe_{2} within the anomalous Hall metal parent state [Xu et al., arXiv:2504.06972.]. Key signatures-including a fully spin and valley-polarized normal state, anomalous Hall resistivity hysteresis, superconducting phase adjacent to the fractional Chern insulating state, and a narrow superconducting dome at zero gating field-collectively indicate chiral superconductivity driven by intravalley pairing of electrons. Within the Kohn-Luttinger mechanism, we compute the superconducting phase diagram via random phase approximation, incorporating Coulomb repulsion in a realistic continuum model. Our results identify a dominant intravalley pairing with a narrow superconducting dome of p+ip type at zero gating field. This chiral phase contrasts sharply with the much weaker time-reversal-symmetric intervalley pairing at finite gating field. Our Letter highlights the role of band topology in achieving topological superconductivity and reveals the chiral and topological nature of the superconductivity observed in twisted MoTe_{2}.
