论文摘要
采用贝斯ANSATZ方法和颗粒位置测量值的数值模拟，我们研究了敌对后的多体动力学，即在环上吸引人相互作用的玻色子，这在平均场方法中对应于所谓的呼吸溶液。尽管最初的多体基态在翻译上是不变的，但如果提取了系统质量中心的量子波动，则测量结果揭示了呼吸动力学。此外，对多体演化的分析显示了形成呼吸器的孤子的解离的特征。
Employing the Bethe ansatz approach and numerical simulations of measurements of particles' positions we investigate a post-quench many-body dynamics of attractively interacting bosons on a ring, which in the mean-field approach corresponds to the so-called breather solution. Despite the fact that the initial many-body ground state is translationally invariant, the measurements reveal breather dynamics if quantum fluctuations of the center of mass of the system are extracted. Moreover, the analysis of the many-body evolution shows signatures of dissociation of the solitons that form the breather.
