我们讨论了极化图作为模拟经典XY模型和Kuramoto模型的新平台。通过抽运激光的空间调制,可以将极化子凝聚体刻印到任意二维图形中。极化子模拟器有可能通过自下而上的方法逐渐增加激发密度达到阈值,从而达到XY哈密顿量的全局最小值,或者研究在阈值以上运行时的大规模同步现象和动态相变。我们考虑用复金兹堡-朗道模型来建模极化子图,并推导了单凝聚体、XY模型、双模模型和Kuramoto模型的解析解,建立了它们之间的关系。
We discuss polariton graphs as a new platform for simulating the classical XY and Kuramoto models. Polariton condensates can be imprinted into any two-dimensional graph by spatial modulation of the pumping laser. Polariton simulators have the potential to reach the global minimum of the XY Hamiltonian in a bottom-up approach by gradually increasing excitation density to threshold or to study large scale synchronization phenomena and dynamical phase transitions when operating above the threshold. We consider the modelling of polariton graphs using the complex Ginzburg–Landau model and derive analytical solutions for a single condensate, the XY model, two-mode model and the Kuramoto model establishing the relationships between them.
