出于宇宙学的例子，我们研究量子场论隧道从初始状态的“经典场”，即真空期望值的字段操作员是空间均匀的，但执行一个依赖于时间的振荡的局部最小值。特别是，我们估计分析和数值的指数贡献的隧穿概率。我们还表明，隧道事件后，经典的场解-所谓的“气泡”-调解相变可以增长或崩溃。我们提出了一个简单的分析标准来区分这两种行为。
Motivated by cosmological examples we study quantum field theoretical tunnelling from an initial state where the "classical field", i.e. the vacuum expectation value of the field operator is spatially homogeneous but performing a time-dependent oscillation about a local minimum. In particular we estimate both analytically and numerically the exponential contribution to the tunnelling probability. We additionally show that after the tunnelling event, the classical field solution - the so-called "bubble" - mediating the phase transition can either grow or collapse. We present a simple analytical criterium to distinguish between the two behaviours.
