锂修饰石墨烯超导体中非绝热效应的可扩展性
Scalability of non-adiabatic effects in lithium-decorated graphene superconductor
摘要:
分析揭示了锂修饰石墨烯(LiC $_{6}$)超导相内的非绝热效应如何缩放。基于Eliashberg形式主义,它表明,非绝热效应显着降低的基本超导参数在LiC $_{6}$和出现作为一个重要的压迫者所讨论的阶段。此外,nonadiabaticity被发现规模与超导电性的强度,成比例的声子能量尺度和相反的电子-声子耦合。这些发现部分地与其他理论研究相反,并表明LiC $_{6}$中的超导性比以前预期的更奇特。在此背景下,在LiC $_{6}$和兄弟材料中增强超导相的准则也被提出。
英文摘要:
The analysis is conducted to unveil how the non-adiabatic effects scale within the superconducting phase of lithium-decorated graphene (LiC$_{6}$). Based on the Eliashberg formalism it is shown that the non-adiabatic effects notably reduce essential superconducting parameters in LiC$_{6}$ and arise as a significant oppressor of the discussed phase. Moreover, nonadiabaticity is found to scale with the strength of superconductivity, proportionally to the phonon energy scale and inversely with respect to the electron-phonon coupling. These findings are partially in contrast to other theoretical studies and show that superconductivity in LiC$_{6}$ is more peculiar than previously anticipated. In this context, the guidelines for enhancing superconducting phase in LiC$_{6}$ and sibling materials are also proposed.
