计算超导转变温度的注记:非绝热区中相互作用的费米气体和声子机制

Notes on calculating temperature of the superconducting transition: interacting fermi gas and phonon mechanisms in non-adiabatic regime

Lev P. Gor'kov

摘要:

本文分析了费米粒子相互作用气体或非绝热条件下金属中声子介导配对的超导转变温度T_c方程的数学结构。例如,当特征声子频率与费米能相当或大于费米能时。在数值近似下导出了Tc的积分方程。方程在反绝热极限中不含发散项。

英文摘要:

We analyze the mathematical structure of equations for temperature Tc of the superconductivity transition in a gas of interacting Fermi particles or at the phonon-mediated pairing in a metal in case of non-adiabatic conditions, i. e., when the characteristic phonon frequency is comparable or larger than the Fermi energy . The integral equations for Tc are derived in the logarithmical approximation. The equations contain no divergent terms in the anti-adiabatic limit.
