我们提出了一个理论的成核在一级相变的调解力是长程的。我们发现，长程力诱导合作的成核和生长过程中，这种反馈机制产生了一个明确的延迟时间与急剧的转变到稳定相。特征的起始时间和宽度的过渡的封闭形式的表达式的开发，与数值计算和现有的实验结果吻合良好。
We present a theory for nucleation at a first-order phase transition where the mediating forces are long range. We find that the long-range force induces cooperative nucleation and growth processes, and that this feedback mechanism produces a well-defined delay time with a sharp onset in the transformation to the stable phase. Closed-form expressions for the characteristic onset time and width of the transition are developed, in good agreement with numerical and existing experimental results.
