我们研究了在具有短程相互作用且没有任何先验淬灭无序的晶格模型中突然冷却后玻璃态的出现。只要平衡模型在低温下拥有足够数量的共存晶相，只要在无限时间限制之前取得热力学极限，就会出现玻璃态。该结果是通过对标准 Potts 模型和一些在方晶格上配备局部随机动力学的排除模型的时间弛豫进行模拟而获得的。
We study the emergence of glassy states after a sudden cooling in lattice models with short-range interactions and without any a priori quenched disorder. The glassy state emerges whenever the equilibrium model possesses a sufficient number of coexisting crystalline phases at low temperatures, provided the thermodynamic limit be taken before the infinite time limit. This result is obtained through simulations of the time relaxation of the standard Potts model and some exclusion models equipped with a local stochastic dynamics on a square lattice.
