论文摘要
基于弱耦合计算,我们表明,在平方晶格上排斥哈伯德模型的准1D极限中,偶数和奇数超导之间出现了意外变性。我们提出,这种效果可能会在quasi-1d轨道上发挥作用,ru $ d_ {zx} $和$ d_ {zy} $ sr2RUO4,从而导致形式的差距$Δ_\ text {fevt} + text {fevy} +iδ_δ_Δ_\ text {奇数{奇数{奇数{奇数{奇数{奇数{奇数{奇数{奇数{奇数} $可以帮助调节几个实验结果。
Based on a weak coupling calculation, we show that an accidental degeneracy appears between even- and odd-parity superconductivity in the quasi-1D limit of the repulsive Hubbard model on the square lattice. We propose that this effect could be at play on the quasi-1D orbitals Ru $d_{zx}$ and $d_{zy}$ of Sr2RuO4, leading to a gap of the form $Δ_\text{even} + i Δ_\text{odd}$ which could help reconcile several experimental results.
