铜氧化物Bi2212超导体能隙与声子能量的反相关

Anti-correlation between energy-gap and phonon energy for cuprate Bi2212 superconductor

Wei Fan

摘要:

利用电子-声子机制,我们很好地解释了STM测量的d^2I/dV^2谱中发现的铜氧化物超导体的能隙与声子模能量之间的空间反相关关系[Jinho Lee,et.al Nature { \bf 442},546(2006)],这是$M<ω^{2}>λ=const$关系的直接结果.我们计算了$λ-Ω_{P}$平面上的T $_{C}$映射,这有助于我们理解M<ω^{2}>λ=const$的关系和超导体的超导电性。

英文摘要:

Using electron-phonon mechanism, we explains very well the spatial anti-orrelation between the energy-gap and the energy of phonon mode for cuprate superconductor found in d^2I/dV^2 spectrum by STM measurements [Jinho Lee, et.al Nature {\bf 442},546 (2006)], which is the direct effect of a relation $M<ω^{2}>λ=const$. We calculate T$_{C}$ maps on $λ-Ω_{P}$ plane which help us understanding the relation M<ω^{2}>λ=const$ and the superconductivity of superconductors.
