使用多维波函数形式，我们研究了在平坦时空中通过假真空衰变成核的真真空气泡内标量场的量子态。我们开发了一种形式主义，使我们能够进行逐个模式的分析。为了证明其优势，我们用个体模式函数详细描述了隧道过程中量子态的演化，并用粒子创造的语言解释了结果。根据米尔恩宇宙中的量子场论对所产生的粒子的光谱进行检查。
Using the multi-dimensional wave function formalism, we investigate the quantum state of a scalar field inside a true vacuum bubble nucleated through false vacuum decay in flat spacetime. We developed a formalism which allows us a mode-by-mode analysis. To demonstrate its advantage, we describe in detail the evolution of the quantum state during the tunneling process in terms of individual mode functions and interpret the result in the language of particle creation. The spectrum of the created particles is examined based on quantum field theory in the Milne universe.
