我们研究了随机多项式势的相对极小值的可能性,以支持通货膨胀的慢滚条件。与重整化和有界性一致,势中出现的系数被选为相对于暴涨发生的能量标度的一阶。对单场情况的研究显示了一个电势满足慢滚条件的窗口。当有两个标量场时,我们发现概率与系数分布的选择略有关系。均匀分布产生在随机势中找到合适最小值的0.05%的概率,而最大熵分布产生0.1%的概率。
We study the likelihood for relative minima of random polynomial potentials to support the slow-roll conditions for inflation. Consistent with renormalizability and boundedness, the coefficients that appear in the potential are chosen to be order one with respect to the energy scale at which inflation transpires. Investigation of the single field case illustrates a window in which the potentials satisfy the slow-roll conditions. When there are two scalar fields, we find that the probability depends mildly on the choice of distribution for the coefficients. A uniform distribution yields a 0.05% probability of finding a suitable minimum in the random potential, whereas a maximum entropy distribution yields a 0.1% probability.
