论文摘要
我们通过淬灭Bose-Einstein凝结物中相互作用的强度,并以有吸引力的相互作用来报告“呼吸器”的产生,“呼吸器”。我们表征了所得的呼吸动力学,并量化了限制电势的纵横比的影响,淬火强度以及2-Soliton呼吸器的1d-3d交叉的接近度。我们进一步证明了由更强的相互作用淬灭产生的三丝龙呼吸器的复杂动力学。我们的实验结果与数值模拟很好地比较,为利用物质波呼吸器探索大型多体系统的量子效应提供了途径。
We report the creation of quasi-1D excited matter-wave solitons, "breathers", by quenching the strength of the interactions in a Bose-Einstein condensate with attractive interactions. We characterize the resulting breathing dynamics and quantify the effects of the aspect ratio of the confining potential, the strength of the quench, and the proximity of the 1D-3D crossover for the 2-soliton breather. We furthermore demonstrate the complex dynamics of a 3-soliton breather created by a stronger interaction quench. Our experimental results, which compare well with numerical simulations, provide a pathway for utilizing matter-wave breathers to explore quantum effects in large many-body systems.
