Abstract

We investigate the physical properties of compressed gray phosphorus through density functional plus dynamical mean-field theory, showing self-doping and \(s\)-wave electronic structure reconstruction. At commensurate electron density, the \(3p\) spectrum is shown to be almost unaffected by electronic correlations, however upon self-doping largely the normal and superconducting states. These findings provide a microscopic understanding of pressure-induced hole carrier superconductivity on the normal state coherence of \(s\)-wave superconductors with well-defined Bogoliubov quasiparticles at low temperatures. Upon internal thermalization, the \(s\)-wave superconducting state loses its phase coherence.

加压灰磷的 Landau-Fermi 流动性和 $$s$$ s 波超导特性

摘要

我们通过密度泛函加动态平均场理论研究了压缩灰磷的物理性质，显示了自掺杂和\(s\)波电子结构重建。在相应的电子密度下，\(3p\)谱显示出几乎不受电子相关性的影响，但是在自掺杂时主要是正常和超导状态。这些发现提供了对压力诱导的空穴载流子超导性在低温下具有明确定义的 Bogoliubov 准粒子的\(s\)波超导体的正常状态相干性的微观理解。在内部热化时，\(s\)波超导状态失去其相位相干性。
