论文摘要
在微观模型的范围内考虑了2D准粒子系统中的玻色 - 敏感性。平均场动力学方程是借助Schwinger-keldysh形式主义得出的，并提出了一个简单的模型，该模型允许描述具有各种准粒子衰变速率的系统中冷凝物形成的关键特征。通过分析该方程式的固定溶液，我们获得了准粒子气的相图，在系统的参数空间中找到了双疗法区域。最后，作为我们理论的应用，我们研究了CDTE微腔中2D激子 - 果龙系统的相图。
Bose-condensation in a system of 2D quasiparticles is considered in the scope of a microscopic model. Mean-field dynamical equations are derived with the help of the Schwinger-Keldysh formalism and a simple model is proposed which allows to describe key features of condensate formation in systems with various quasiparticle decay rates. By analysing stationary solutions of this equation, we obtain the phase diagram of quasiparticle gas, finding a bistability region in the parameter space of the system. Finally, as an application of our theory, we study the phase diagram of a 2D exciton-polariton system in CdTe microcavity.
