标题： Artificial Life in an Exciton-Polariton Lattice

摘要： 我们理论上表明，当同时被连续波相干场和非共振脉冲的周期性序列激发时，激子极化子晶格可以表现出类似生命的游戏细胞自动机。 这提供了一种在相同条件下实现一系列高度期望的时空结构的机制，包括：离散孤子、振荡孤子、旋转孤子、呼吸子、孤子束、发生器和混沌行为。 这些结构可以在系统中无限期地存在，尽管存在耗散，并且允许通用计算。 显示英文摘要

摘要： We show theoretically that a lattice of exciton-polaritons can behave as a life-like cellular automaton when simultaneously excited by a continuous wave coherent field and a time-periodic sequence of non-resonant pulses. This provides a mechanism of realizing a range of highly sought spatiotemporal structures under the same conditions, including: discrete solitons, oscillating solitons, rotating solitons, breathers, soliton trains, guns, and choatic behaviour. These structures can survive in the system indefinitely, despite the presence of dissipation, and allow universal computation.
