论文摘要
当合适的订单参数的密度超过临界值时，几种晶格模型在实际空间中显示了凝结过渡。我们在一维开放设置中考虑了一个具有两个保护定律的模型之一，该设置将系统连接到两个外部储层。两个储层都在链端施加了亚临界边界条件。当这种边界条件相等时，系统处于凝结阈值以下的平衡，并且不会出现冷凝水。取而代之的是，当系统脱离平衡时，可能会在晶格的内部部分中进行定位。我们讨论了这种现象的起源，保护定律的数量的相关性以及冷凝物固定对均衡状态动力学的影响。
Several lattice models display a condensation transition in real space when the density of a suitable order parameter exceeds a critical value. We consider one of such models with two conservation laws, in a one-dimensional open setup where the system is attached to two external reservoirs. Both reservoirs impose subcritical boundary conditions at the chain ends. When such boundary conditions are equal, the system is in equilibrium below the condensation threshold and no condensate can appear. Instead, when the system is kept out of equilibrium, localization may arise in an internal portion of the lattice. We discuss the origin of this phenomenon, the relevance of the number of conservation laws, and the effect of the pinning of the condensate on the dynamics of the out-of-equilibrium state.
