论文摘要
旋转三重奏超导性是一种罕见的量子现象。在这里，我们表明，在存在自旋轨道耦合的情况下，非肌晶晶体对称性可以极大地有助于自旋三曲线超导性。即使使用弱的自旋轨道耦合，自旋三个配对也可以是与非词形对称性的晶格中的主要配对不稳定性。下划线的机制是由非词形对称性保护的电子带上的自旋 - 宣传巨头锁。我们使用非畸形空间组P4/NMM来证明这些结果并讨论相关的可观察结果。我们的作品铺平了一种新的方式，以寻找自旋三角体超导性。
Spin-triplet superconductivity is known to be a rare quantum phenomenon. Here we show that nonsymmorphic crystalline symmetries can dramatically assist spin-triplet superconductivity in the presence of spin-orbit coupling. Even with a weak spin-orbit coupling, the spin-triplet pairing can be the leading pairing instability in a lattice with a nonsymmorphic symmetry. The underlining mechanism is the spin-sublattice-momentum lock on electronic bands that are protected by the nonsymmorphic symmetry. We use the nonsymmorphic space group P4/nmm to demonstrate these results and discuss related experimental observables. Our work paves a new way in searching for spin-triplet superconductivity.
