By using numerical method, the superconducting critical temperature Tc is cal-culated from the Eliashberg equation and the dependence of Tc on λ and the shape of effective phonon spectrum is investigated. In this study, α2F(ω) is taken as the double delta-function spectrum and the spectrum parameters are permited to change over a wide range. It is found with surprising that in the regime of λ < (?), i.e. outside the convergence circle of the Tc series solution, Tc depends, not only on λ and ratios of moments...

By using numerical method, the superconducting critical temperature Tc is cal-culated from the Eliashberg equation and the dependence of Tc on λ and the shape of effective phonon spectrum is investigated. In this study, α2F(ω) is taken as the double delta-function spectrum and the spectrum parameters are permited to change over a wide range. It is found with surprising that in the regime of λ < (?), i.e. outside the convergence circle of the Tc series solution, Tc depends, not only on λ and ratios of moments but also on (?), the reciprocal of the convergence radius of the Tc series solution, and the relation between them shows a certain regularity. Under the light of these results, an approximate Tc formula for the case of μ* = 0 is constructed in the regime of λ < (?) through fitting the numerical solution of Eliashberg equation,

本文用数值解方法从Eliashberg方程计算出超导临界温度T_c,并考察T_c对有效声子谱的依赖关系。在这个研究中,a~2F(ω)被取为双δ函数谱,并允许其中的谱参数可以在很宽范围内改变。作者发现在λ<∧区域(即在T_c级数解的收敛圆外),T_c除了依赖λ和矩比外,还依赖T_c级数解的收敛半径倒数Λ;它们之间的关系是有规律的。在这些结果的启示下,本文在μ=0情形,用弥合数值解的方法得到一个适用于λ<Λ区域的T_c近似公式。 接着,本文作者对吉光达和吴杭生的一篇文章进行了研究,指出:该文提出的超导体分类建议及其工作的主要结论是对的。但其中对决定A型超导体临界温度主要参量问题进行的分析,只适用于这样一些A型超导体,它们的收敛半径倒数Λ或者比λ_0小,或者虽比λ_0大、但λ又小于λ_0,其中λ_0是个依赖谱形状的参量,它的定义在正文中给出。对另一些A型超导体(λ_0<λ<Λ),决定T_c的主要参量不再是λ,而是δ=1/∧~(0.5)(_(1/2)/ω_(log))~(5.5)λ~(1.55)。
