包含自洽性的固体脉动电磁场的谱描述

Spectral description of fluctuating electromagnetic fields of solids including a self consistency

Illarion Dorofeyev

摘要:

提出了另一种评价固体热场谱相关特性的方法。这种方法考虑了将一个体区域与真空区域的那些体区域分离的界面过渡层的详细结构。这里的主要元素是固体的任意非均匀电子子系统的表面线性响应函数。除了直接使用已知的响应函数外,例如在流体动力学方法中,所建议的方法允许基于时间相关的密度泛函理论自洽地计算响应函数。线性响应函数的自洽计算,然后应用波动耗散定理产生的波动电荷和电流的关联函数的谱功率密度。这一系列行动的最后一步,旨在获得在任何距离的固体热场的光谱相关特性。

英文摘要:

Another way to evaluate the spectral-correlation properties of thermal fields of solids is suggested. Such a method takes into account detailed structure of the interface transition layer separating one bulk region from those of the vacuum region. The principal element here is the surface linear response function of an arbitrary inhomogeneous electron subsystem of solids. Along with straightforward using the known response functions, for example in a hydrodynamic approach, the suggested method allows calculating the response functions self-consistently based on the time dependent density functional theory. The self-consistent calculation of the linear response function followed by an application of the fluctuation-dissipation theorem yield in the spectral power densities of the fluctuating charge and current correlation functions. The final step of this sequence of actions aiming in obtaining the spectral-correlation properties of thermal fields of solids at any distances.
