论文摘要
我们预测介质结合状态的二元散射期间的超倾斜产生，玻色网凝管中的孤立波，其中包含数千个相同的玻色子。潜在的多体哈密顿量不得整合，并且孤子的前量子状态碎片。在这些条件下，我们使用纯状态量子场模拟显示，对于逼真的参数，圆柱后状态将在孤子中的空间自由度和原子数中超出范围。该效果将非线性系统的各个方面与量子碳的各个方面以及纠缠后的状态挑战相同颗粒的纠缠标准。我们的结果基于使用截短的Wigner近似值，基于在平均场之外的Quintic相互作用模型中碰撞量子孤子的模拟。
We predict hyper-entanglement generation during binary scattering of mesoscopic bound states, solitary waves in Bose-Einstein condensates containing thousands of identical Bosons. The underlying many-body Hamiltonian must not be integrable, and the pre-collision quantum state of the solitons fragmented. Under these conditions, we show with pure state quantum field simulations that the post-collision state will be hyper-entangled in spatial degrees of freedom and atom number within solitons, for realistic parameters. The effect links aspects of non-linear systems and quantum-coherence and the entangled post-collision state challenges present entanglement criteria for identical particles. Our results are based on simulations of colliding quantum solitons in a quintic interaction model beyond the mean-field, using the truncated Wigner approximation.
