论文摘要
临界温度的变化$ t_c $和平面临界场$ h_ {c2} $的$ \ text {sr} _2 \ text {ru} \ text {ru} \ text {o} _4 $在单轴压力下已报告。我们将$ t_c $和$ h_ {c2} $的应变依赖性（$ d $ - 波，扩展S-Wave和$ p $ - 波）与实验观测值进行了研究，通过研究一个三频紧密结合模型，其中包括Spin-Orbit和Zeeman和Zeeman couplings和可分离的配对互动的效果。我们的研究有助于缩小配对通道的可能性。 $ \ text {sr} _2 \ text {ru} \ text {o} _4 $的多波段性质的重要性也突出显示。
Variations of critical temperature $T_c$ and in-plane critical field $H_{c2}$ of $\text{Sr}_2\text{Ru}\text{O}_4$ under uniaxial stress have recently been reported. We compare the strain dependence of $T_c$ and $H_{c2}$ in various pairing channels ($d$-wave, extended s-wave and $p$-wave) with the experimental observations, by studying a three-band tight-binding model that includes effects of spin-orbit and Zeeman couplings and a separable pairing interaction. Our study helps narrow down the possibility of pairing channels. The importance of the multi-band nature of $\text{Sr}_2\text{Ru}\text{O}_4$ is also highlighted.
