我们给出了声子介导超导的均匀电子气模型的Migdal-Eliashberg方程的完整数值解。我们发现临界温度非常低,低于1K,这与早期认为氢固体的均匀电子气模型可能达到室温超导的说法相反。我们的结果表明,为了准确估计临界温度,应考虑能隙函数和正常自能的完整动量和频率依赖性。
英文摘要
We present a full numerical solution of the Migdal--Eliashberg equations for the jellium model of phonon-mediated superconductivity. We find very low critical temperatures below 1~K, in contrast to earlier claims that the jellium model for hydrogen solids might reach room-temperature superconductivity. Our results suggest that full momentum and frequency dependence of the gap function and normal self-energy should be taken into account for accurate $T_c$ estimates.
