Laser操作与玻色-爱因斯坦凝聚:类比与区别

Laser operation and Bose-Einstein condensation: analogies and differences

Alessio Chiocchetta, Andrea Gambassi, Iacopo Carusotto

摘要:

在回顾了将激光运转解释为非平衡态玻色-爱因斯坦凝聚相变之后,我们阐述了最近在实验中观察到的光子和极化激元玻色-爱因斯坦凝聚体的非平衡性质所产生的新特征。然后,我们prosea定量标准,实验评估的平衡与非平衡性质的一个特定的冷凝过程,波动耗散关系的基础上。这一标准的力量是说明两个模型,表现出非常不同的行为。

英文摘要:

After reviewing the interpretation of laser operation as a non-equilibrium Bose-Einstein condensation phase transition, we illustrate the novel features arising from the non-equilibrium nature of photon and polariton Bose-Einstein condensates recently observed in experiments. We then proposea quantitative criterion to experimentally assess the equilibrium vs. non-equilibrium nature of a specific condensation process, based on fluctuation-dissipation relations. The power of this criterion is illustrated on two models which shows very different behaviours.
