论文摘要
我们描述了一种仅使用各向同性S波散射长度的淬灭的准盒子捕获的玻璃纤维凝结物中制备孤子的方案。淬灭的四倍，最初的1D耦合强度在盒子的每个边界上产生一个孤子，然后在均匀的背景密度中传播，并相互碰撞。在淬火期间没有产生非核激发。该过程与散射长度坡道速率的缺陷和最终散射长度的不匹配是可靠的。
We describe a protocol to prepare solitons in a quasi-1d box-trapped Bose-Einstein condensate using only a quench of the isotropic s-wave scattering length. A quench to exactly four times the initial 1d coupling strength creates one soliton at each boundary of the box, which then propagate in a uniform background density and collide with one another. No nonsolotonic excitations are created during the quench. The procedure is robust against imperfections in the scattering length ramp rate and a mismatch of the final scattering length.
