This study investigates a strongly interacting many-body system of bosons using Gaudin solutions, revealing that a highly coherent design present in an ultracold bosonic gas trapped in a box potential gets destroyed by weak to moderate interatomic interactions, but is revived in a very strongly interacting regime. The analysis tracks the crossover from single- to many-body systems and examines de- and rephasing in the system.
A 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.
