论文摘要
我们表明，可以通过在标量电位中引入合适的扁平区域来机械确定小场通货膨胀的初始条件。然后将充气驱动到缓慢的吸引子解决方案呈指数速度，从初始速度脱敏通货膨胀，并部分逃避所谓的过时问题。我们在山顶通胀的背景下给出了一个明确的例子，它通过在最大值的最大值上引入一个超慢滚水，并分析其对相位轨迹的影响。
We show that initial conditions for small-field inflation can be determined quantum mechanically by introducing a suitable flattened region in the scalar potential. The inflaton is then driven towards the slow-roll attractor solution exponentially fast, desensitising inflation from the initial velocity and partially evading the so-called overshoot problem. We give an explicit example in the context of hilltop inflation by introducing an ultra slow-roll plateau around the maximum of the potential and analyse its effect on the phase-space trajectories.
