论文摘要
通过使用高丁溶液，精确研究了表现出量子地毯图案的玻色子的强烈相互作用的多体系统。我们表明，这种高度连贯的设计通常存在于非相互作用的单体场景中，被薄弱至中度的在盒子潜力中的超低玻色子气体中被弱至中度的原子间相互作用破坏。但是，当系统经历费米化时，它会在非常强烈的互动状态下复活。我们跟踪整个单体跨界的整个单体跨界，提供了系统中存在和重塑的分析。
Strongly interacting many-body system of bosons exhibiting the quantum carpet pattern is investigated exactly by using Gaudin solutions. We show that this highly coherent design usually present in noninteracting, single-body scenarios gets destroyed by weak-to-moderate interatomic interactions in an ultracold bosonic gas trapped in a box potential. However, it becomes revived in a very strongly interacting regime, when the system undergoes fermionization. We track the whole single- to many-body crossover, providing an analysis of de- and rephasing present in the system.
