论文摘要
我们研究了三维(3D)极性系统中具有可调色散参数的电子特性和电子相关性。二极管耦合被认为是一种弱吸引人的裸耦合。本文都考虑了单极和多极龙,零和有限温度的情况。研究了物理量,包括自我能源,光谱函数,光导率(平面和3D 1),自由能和动量分布函数,并经过验证。分析推导和数值计算均在本文中完成,以使我们的结果可靠。
We investigate the electronic properties and electron correlations in a three-dimensional (3D) polaron system with tunable dispersion parameter in Fermi-liquid picture. The polaronic coupling is considered as a weakly attractive bare coupling. Both the single and many-polaron, zero and finite-temperature cases are considered in this paper. The physical quantities, including the self-energy, spectral function, optical conductivity (both the planar and 3D one), free energy, and momentum distribution function, are studied and are been verified exhibit Fermi-liquid features. Both the analytic derivation and numerical calculation are done in this paper to make our results reliable.
