论文摘要
Landau-Ginzburg $ ϕ^4 $场理论通常应用于系统，以理解关键点的连续相变。在这里，我们从统计场理论的角度使用类似的自由能描述分析了热场，并在此类领域中研究波动，特别着眼于实现热Casimir效应。最初，我们使用均值场近似定性地描述了类似Casimir的效应的出现，并使用高斯固定点附近的扰动重新分配程序的粗粒度进一步得出了它。这些结果可能会进一步进一步理解标量场的Casimir效应，而无需在宇宙学意义上采用零点能量的概念。
Landau-Ginzburg $ϕ^4$ field theory is usually applied to systems for understanding continuous phase transitions at critical points. Here we analyze the thermal field using a similar free energy description from a statistical field theory perspective, and study fluctuations in such a field with a particular focus on realizing the thermal Casimir effect. Initially, we qualitatively describe the emergence of the Casimir-like effect using mean-field approximation and further derive it using coarse-graining of perturbative renormalization procedure in the vicinity of Gaussian-fixed point. These results may lead to further the understanding of the Casimir effect from scalar fields without employing the concept of zero-point energy in a cosmological sense.
