Kinetic traps are a notorious problem in equilibrium statistical mechanics, where temperature quenches ultimately fail to bring the system to low energy configurations. Using multifarious self-assembly as a model system, we introduce a mechanism to escape kinetic traps by utilizing nonreciprocal interactions between components. Introducing nonequilibrium effects offered by broken action-reaction symmetry in the system pushes the trajectory of the system out of arrested dynamics. The dynamics of the model is studied using tools from the physics of interfaces and defects. Our proposal can find applications in self-assembly, glassy systems, and systems with arrested dynamics to facilitate escape from local minima in rough energy landscapes.
动力学陷阱是平衡统计力学中一个声名狼藉的问题，在这种情况下，温度猝灭最终无法使系统达到低能量构型。我们以多种自组装作为模型系统，引入一种机制，通过利用组件之间的非互易相互作用来逃离动力学陷阱。引入系统中作用 - 反作用对称性破缺所提供的非平衡效应，可将系统轨迹推出停滞动力学状态。我们使用界面与缺陷物理学的工具来研究该模型的动力学。我们的提议可应用于自组装、玻璃态系统以及具有停滞动力学的系统，以促进在粗糙能量景观中从局部最小值中逃离。
