电子-声子超导体最高Transition-temperature的预测

Predictions of highest Transition-temperature for electron-phonon superconductors

Wei Fan

摘要:

利用带顶点修正的Eliashberg强耦合理论,计算了全参数空间中电子-声子超导体的转变温度(T $_{c}$).根据这些图和超导不稳定性判据,预测了超导体的最大转变温度。在超导体中,强的顶点修正和高的转变温度是紧密相关的。我们预测新铁基超导体的T $_{c}$的最大值将接近90(K)。

英文摘要:

Using the Eliashberg strong coupling theory with vertex correction, we calculate maps of transition temperatures (T$_{c}$) of electron-phonon superconductors in full parameter space. The maximums of transition temperatures for superconductors are predicted based on the maps and the criterion of instability of superconductivity. The strong vertex correction and high transition temperature are tightly correlated in superconductors. We predict that the maximum of T$_{c}$ of new iron-based superconductors will be close to 90(K).
