The periodically kicked rotor serves as a paradigmatic model for studying chaos. While the classical regime exhibits chaotic behavior, quantum coherence introduces a fascinating phenomenon: Anderson-like localization in momentum space for its quantum counterpart. Moving beyond the single quantum rotor or single-particle scenario, the complexity increases significantly when considering strongly interacting quantum many-body systems. This raises crucial questions: Does strong particle-particle interaction preserve dynamical localization? Or, more importantly, what role does interaction play in this context? In this talk, we will address these questions by investigating the kicked Lieb-Liniger model beyond the mean-field regime. We will explore the conditions of many-body dynamical localization.
