我们给出了广义相对论中真假真空衰减率的一种新颖、简明和完备的评估方法。我们坚持广义协方差,并选择了可观测的边界条件,从而得到了众所周知的伪真空衰减率和新的真真空衰减率,它与以前的工作有很大的不同。在广义相对论中,真假真空衰变率是相同的。动作的第二个变化对所有参数都具有负模式。我们的发现暗示着对宇宙初始条件和我们宇宙的最终命运的新视角。
We provide a novel, concise and self-contained evaluation of true- and false vacuum decay rates in general relativity. We insist on general covariance and choose observable boundary conditions, which yields the well known false-vacuum decay rate and a new true-vacuum decay rate that differs significantly from prior work. The rates of true- and false vacuum decays are identical in general relativity. The second variation of the action has a negative mode for all parameters. Our findings imply a new perspective on cosmological initial conditions and the ultimate fate of our universe.
