极化激元凝聚的随机经典场模型
Stochastic classical field model for polariton condensates
摘要：
我们利用截断维格纳近似推导出描述极化激元凝聚的随机经典场方程。在低极化激元密度的极限下，我们的方程可简化为玻尔兹曼方程。利用蒙特卡罗模拟分析了粒子密度在凝聚阈值范围内变化时的动量分布和一阶、二阶相干性。
英文摘要：
We use the truncated Wigner approximation to derive stochastic classical field equations for the description of polariton condensates. Our equations are shown to reduce to the Boltzmann equation in the limit of low polariton density. Monte Carlo simulations are performed to analyze the momentum distribution and the first and second order coherence when the particle density is varied across the condensation threshold.
