论文摘要
我们提出了一种检测排斥一维和谐波捕获的bose-Einstein冷凝物中深色孤子的存在和深度的方法。对于具有一个孤子的系统，我们证明傅立叶空间中密度的移位直接映射到孤子深度上。对于多功能系统，将我们的光谱方法与已建立的成像技术相结合，可以确定冷凝水中存在的孤子的特征。我们验证在密度工程方法引起的波浪的存在下，通过光谱移位检测孤子。最后，我们讨论了在三维玻色网凝结物中对涡旋检测的含义。
We present a method to detect the presence and depth of dark solitons within repulsive one-dimensional harmonically trapped Bose-Einstein condensates. For a system with one soliton, we prove that the shift of the density in Fourier space directly maps onto the depth of the soliton. For multi-soliton systems, combining our spectral method with established imaging techniques, the character of the solitons present in the condensate can be determined. We verify that the detection of solitons by the spectral shift works in the presence of waves induced by density engineering methods. Finally we discuss implications for vortex detection in three dimensional Bose-Einstein condensates.
