We use the functional renormalization group method to study a three-orbital model for superconducting Sr_{2}RuO_{4}. Although the pairing symmetry is found to be a chiral p wave, the atomic spin-orbit coupling induces near nodes for quasiparticle excitations. Our theory explains a major experimental puzzle between a d-wavelike feature observed in thermal experiments and the chiral p-wave triplet pairing revealed in nuclear-magnetic resonance and the Kerr effect.
我们使用泛函重整化群方法研究超导 Sr_{2}RuO_{4} 的一个三能带模型。尽管配对对称性被发现是手性 p 波，但原子自旋轨道耦合导致准粒子激发在近节点处出现。我们的理论解释了热实验中观察到的 d 波特征与核磁共振和克尔效应揭示的手性 p 波三重态配对之间的一个主要实验难题。
