我们提出了一种方法，将相互吸引的玻色-爱因斯坦凝聚体的基态分裂成两个具有受控相对相位和速度的明亮孤立波。我们分析了这些波的稳定性，对他们随后在一个圆柱对称的，扁长的谐波陷阱作为相对相位，速度和陷阱的各向异性的函数的中心delicilisions。我们发现，碰撞稳定性是强烈依赖于相对相位在低速度，我们确定以前未观察到的振荡的碰撞稳定性作为陷阱各向异性的函数。我们的方法的实验实施将确定的有效性的平均场描述的明亮的孤立波，并可能被证明是一个重要的一步，原子干涉实验涉及明亮的孤立波。
We propose a method to split the ground state of an attractively interacting atomic Bose-Einstein condensate into two bright solitary waves with controlled relative phase and velocity. We analyze the stability of these waves against their subsequent recollisions at the center of a cylindrically symmetric, prolate harmonic trap as a function of relative phase, velocity, and trap anisotropy. We show that the collisional stability is strongly dependent on relative phase at low velocity, and we identify previously unobserved oscillations in the collisional stability as a function of the trap anisotropy. An experimental implementation of our method would determine the validity of the mean-field description of bright solitary waves and could prove to be an important step toward atom interferometry experiments involving bright solitary waves.
