The East model has a dynamical phase transition between an active (fluid) and inactive (glass) state. We show that this phase transition generalizes to "softened" systems where constraint violations are allowed with small but finite probabilities. Moreover, we show that the first order coexistence line separating the active and inactive phases terminates in a finite-temperature space-time critical point. Implications of these results for equilibrium dynamics are discussed.
东方模型在活性（流体）和非活性（玻璃）状态之间存在动力学相变。我们表明，这种相变推广到允许约束违反以小但有限的概率发生的“软化”系统。此外，我们表明，分离活性和非活性相的一级共存线在有限温度时空临界点处终止。这些结果对平衡动力学的影响进行了讨论。
