论文摘要
在这项工作中，我们研究了在高衍生电动力学的背景下，在热浴中光子气体的热力学特性。具体而言，我们分析了Podolsky的理论及其扩展，涉及文献中最近提出的Lorentz对称性违规行为。首先，我们使用系统可用状态数量的概念来构建分区功能。接下来，我们计算主要的热力学功能：Helmholtz自由能，平均能量，熵和热容量。特别是，我们验证是否由于洛伦兹违规而导致的热容量和平均能量存在重大变化。此外，在原始通货膨胀宇宙的背景下，也为黑体辐射的修改和对Stefan-Boltzmann定律的校正也为理论提供了。
In this work, we study the thermodynamic properties of a photon gas in a heat bath within the context of higher-derivative electrodynamics. Specifically, we analyze Podolsky's theory and its extension involving the Lorentz symmetry violation recently proposed in the literature. First, we use the concept of the number of available states of the system in order to construct the partition function. Next, we calculate the main thermodynamic functions: Helmholtz free energy, mean energy, entropy, and heat capacity. In particular, we verify that there exist significant changes in heat capacity and mean energy due to Lorentz violation. Additionally, the modification of the black body radiation and the correction to the Stefan-Boltzmann law in the context of the primordial inflationary universe are provided for both theories as well.
