论文摘要
我们研究通货膨胀的几何不稳定，目的是确定激发不稳定模式的命运。我们使用数值晶格模拟来跟踪Adflaton和观众场的动力学。我们发现几何不稳定是一种短暂的现象，而负反馈回路可以防止场波动无限期地增长。结果，经历几何稳定的字段仅移至与哈勃贴片中观众场均匀值相对应的新的经典配置。
We study geometrical destabilization of inflation with the aim of determining the fate of excited unstable modes. We use numerical lattice simulations to track the dynamics of both the inflaton and the spectator field. We find that geometrical destabilization is a short-lived phenomenon and that a negative feedback loop prevents field fluctuations from growing indefinitely. As a result, fields undergoing geometrical destabilization are merely shifted to a new classical configuration corresponding to a uniform value of the spectator field within a Hubble patch.
