论文摘要
我们计算了平面零散的静态Quasi-Two-two-didy-wo（Q2D）手性三重导体超导体在零温度下，$ t = 0 $的平面临界磁场$ h _ {\ Parallel}（0）$。特别是，定义了比率$ h _ {\ PARALELL}（0）/（| dh^{gl} _ {\ parlallel}/dt | _ {t = t_c} t_c）= 0.815 $定义了上临界磁场的Ginzburg-Landau坡度，$ t_c $是$ h = 0 $的超导过渡温度。我们表明，在候选人中，在候选人中，获得的上述价值与手性三重导体超导性SR $ _2 $ ruo $ _4 $强烈矛盾，这在这种化合物中提供了另一种论点。我们的结果可能有助于在此现象中其他Q2D候选者中建立手性三重超导性。
We calculate the parallel upper critical magnetic field $H_{\parallel}(0)$ for an in-plane isotropic quasi-two-dimensional (Q2D) chiral triplet superconductor at zero temperature, $T=0$. In particular, the ratio $H_{\parallel}(0)/(|dH^{GL}_{\parallel}/dT|_{T=T_c}T_c) = 0.815$ is defined, where $|dH^{GL}_{\parallel}/dT|_{T=T_c}$ is the so-called Ginzburg-Landau slope of the upper critical magnetic field, $T_c$ is a superconducting transition temperature at $H=0$. We show that the theoretically obtained above mentioned value strongly contradicts to the experimentally measured ones in a candidate for a chiral triplet superconductivity Sr$_2$RuO$_4$, which provides one more argument against the chiral triplet scenario of superconductivity in this compound. Our results may be useful for establishing chiral triplet superconductivity in other Q2D candidates for this phenomenon.
