中文摘要：

我们调查多重部件的电子偶素冷凝物的腐烂的量动力学进一些光子。一个电子偶素原子有通过 s 波浪相互作用可互相转的四个内部旋转状态。电子偶素和光子的所有旋转状态的量地用截断的 Wigner 方法在 quasi-one-dimensional 系统从第一个原则被模仿。这个方法保证我们混合的电子偶素领域和旋转的弄空的一个完整的处理由在电子偶素原子之间的 s 波浪碰撞导致了。特别地，它产出射出的光子和光子光子关联的动量光谱。

英文摘要：

We investigate the quantum dynamics of the decay of a multiple-component positronium condensate into pairs of photons. A positronium atom has four internal spin states which are interconvertible through s-wave interactions. The quantum fields of all spin states of positroniums and photons are simulated from first principle in quasi-one-dimensional system using the truncated Wigner method. This method warrants us a full treatment of the depletion of positronium fields and the spin mixing induced by s-wave collisions between positronium atoms. Particularly,it yields the momentum spectrum of the emitted photons and the photon-photon correlations.
