一个经典场论可能有两个稳定的均匀基态，其中只有一个是绝对能量最小值。在该理论的量子版本中，高能量的基态是一个假真空，由于势垒穿透而变得不稳定。关于这种假真空的衰变，存在着一种公认的半经典理论。在本文中，我们将这一理论扩展到包括引力效应。与天真的期望相反，这些并不总是可以忽略不计的，有时可能至关重要，特别是在衰变过程的后期阶段。
It is possible for a classical field theory to have two stable homogeneous ground states, only one of which is an absolute energy minimum. In the quantum version of the theory, the ground state of higher energy is a false vacuum, rendered unstable by barrier penetration. There exists a well-established semiclassical theory of the decay of such false vacuums. In this paper, we extend this theory to include the effects of gravitation. Contrary to naive expectation, these are not always negligible, and may sometimes be of critical importance, especially in the late stages of the decay process.
