我们重新审视准一维系统中的配对对称性竞争。我们证明，当电荷波动强度超过自旋波动强度时，在一维系统中可以实现自旋三重态波配对，其中该对由不同时间的电子形成并具有奇频对称性。本研究为 Berezinskii 提出的这种奇异配对提供了一种机制 [JETP Lett. 20, 287 (1974)]。
We revisit the pairing symmetry competition in quasi-one-dimensional systems. We show that spin-triplet-wave pairing, where the pair is formed by electrons with different times and has an odd-frequency symmetry, can be realized in systems with one-dimensionality when the strength of charge fluctuation exceeds that of spin fluctuation. The present study provides a mechanism for this exotic pairing proposed by Berezinskii [JETP Lett. 20, 287 (1974)].
