论文摘要
我们基于一个尺寸的两个组分玻色气体对早期宇宙相变的类似物进行了对超冷状态的分析。我们证明，组件之间相对相的热波动是相对论热系统的特征。此外，我们证明了两种不同的方法对亚稳态的衰变的等效性：特别是非扰动热插入计算和随机毛 - 彼得泰夫斯基仿真。
We perform an analysis of the supercooled state in an analogue to an early universe phase transition based on a one dimensional, two-component Bose gas. We demonstrate that the thermal fluctuations in the relative phase between the components are characteristic of a relativistic thermal system. Furthermore, we demonstrate the equivalence of two different approaches to the decay of the metastable state: specifically a non-perturbative thermal instanton calculation and a stochastic Gross--Pitaevskii simulation.
