论文摘要
本文的目的是通过量子场理论的有效潜在方法为重力场构建量子有效作用。量子有效作用的最小值给出了量子波动的方程。我们讨论平坦时空和Schwarzschild时空中的量子波动。结果表明，可以通过量子波动从经典真空中创建婴儿时空。
The aim of this paper is to construct a quantum effective action for gravitational fields by the effective potential method in quantum field theory. The minimum of the quantum effective action gives an equation of quantum fluctuations. We discuss the quantum fluctuation in the flat spacetime and in the Schwarzschild spacetime. It is shown that a baby spacetime may be created from a classical vacuum through a quantum fluctuation.
