Abstract

The consideration of equilibrium radiation in plasma-like media shows that the spectral energy distribution of such radiation differs from that of Planck equilibrium radiation. Based on the previously derived relation for the spectral energy density of equilibrium radiation in the system of charged particles, accounting for finite damping in a medium with spatial dispersion, the limiting case of infinitesimal damping dispersion is considered. It was shown that zero-point vacuum fluctuations being a component of the total spectral energy distribution in the medium should be renormalized when using certain models for the transverse plasma permittivity. In this case, renormalized zero-point vacuum fluctuations become dependent on plasma parameters. The possibility of the manifestation of this effect is discussed.

库仑系统平衡辐射和零点涨落的光谱分布

摘要

对类等离子体介质中平衡辐射的考虑表明，这种辐射的光谱能量分布与普朗克平衡辐射的光谱能量分布不同。基于先前导出的带电粒子系统中平衡辐射的光谱能量密度的关系，考虑到在具有空间色散的介质中的有限阻尼，考虑了无限小阻尼色散的极限情况。结果表明，当使用某些横向等离子体介电常数模型时，零点真空波动是介质中总光谱能量分布的组成部分，应重新归一化。在这种情况下，重新归一化的零点真空波动将取决于等离子体参数。讨论了这种影响的可能性。
