标题： Chiral superconductivity from spin polarized Chern band in twisted MoTe$_2$

摘要： 在异常霍尔金属母态的双层扭曲MoTe₂中观察到了超导性。 关键特征——包括完全自旋/谷极化的正常态、异常霍尔电阻滞后、与分数陈绝缘态相邻的超导相以及零栅控场下的窄超导尖峰——共同表明由电子的谷内配对驱动的手征超导性。 在科恩-卢廷格机制内，我们通过随机相位近似计算了超导相图，在真实连续模型中考虑了库仑排斥力。 我们的结果确定了在零栅控场下主导的谷内配对和p+ip类型的窄超导尖峰。 这种手征相与有限栅控场下较弱的时间反演对称的谷间配对形成了鲜明对比。 我们的工作突出了能带拓扑在实现稳健的拓扑超导性中的作用，并支持在扭曲MoTe₂中观察到的超导性的手征和拓扑性质。 显示英文摘要

摘要： Superconductivity has been observed in twisted MoTe2 within the anomalous Hall metal parent state. Key signatures-including a fully spin/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 gate field. This chiral phase contrasts sharply with the much weaker time-reversal-symmetric intervalley pairing at finite gating field. Our work highlights the role of band topology in achieving robust topological superconductivity, and supports the chiral and topological nature of the superconductivity observed in twisted MoTe2.
