我们研究了实验上真实的玻色-爱因斯坦凝聚波包之间的碰撞，在形成高度密集的散射晕的区域内进行数值模拟。这项工作的理论基础是截断维格纳方法，我们对此进行了详细的推导，特别关注其碰撞凝聚态的有效性机制。本文是我们上一封信 [A. A. Norrie、R. J. Ballagh 和 C. W. Gardiner，物理学家。莱特牧师。 94, 040401 (2005)]，我们研究了单轨迹解（揭示了散射晕中量子湍流的存在）和轨迹系综（我们用它来计算场的量子力学相关函数）。
We investigate numerically simulated collisions between experimentally realistic Bose-Einstein condensate wave packets, within a regime where highly populated scattering haloes are formed. The theoretical basis for this work is the truncated Wigner method, for which we present a detailed derivation, paying particular attention to its validity regime for colliding condensates. This paper is an extension of our previous Letter [A. A. Norrie, R. J. Ballagh, and C. W. Gardiner, Phys. Rev. Lett. 94, 040401 (2005)], and we investigate both single-trajectory solutions, which reveal the presence of quantum turbulence in the scattering halo, and ensembles of trajectories, which we use to calculate quantum-mechanical correlation functions of the field.
