具有双曲色散关系的光子气体

Photon gas with hyperbolic dispersion relations

Morteza Mohseni

摘要:

本文研究了光子气体在介电常数张量的某些分量为负的介质中的态密度。我们研究了双曲色散关系对黑体谱密度的影响。我们表明,对于这两种可能的波矢空间拓扑结构,在一定的频率谱密度消失。得到了系统的配分函数,并导出了系统的一些物理量。在领先的顺序中,结果类似于具有增强态密度的一维或二维光子气体的结果。

英文摘要:

We investigate the density of states for a photon gas confined in a nonmagnetic metamaterial medium in which some components of the permittivity tensor are negative. We study the effect of the resulting hyperbolic dispersion relations on the black body spectral density. We show that for both of the possible wavevector space topologies, the spectral density vanishes at a certain frequency. We obtain the partition function and derive some thermodynamical quantities of the system. To leading order, the results resemble those of a one- or two-dimensional photon gas with an enhanced density of states.
