• Abstract: Adiabatic passage in systems of interacting bosons is substantially affected by interactions and inter-particle entanglement. We consider STIRAP-like schemes in Bose-Hubbard chains that exhibit low-dimensional chaos (a 3 site chain), and high-dimensional chaos (more than 3 sites). The dynamics that is generated by a transfer protocol exhibits striking classical and quantum chaos fingerprints that are manifest in the mean-field classical treatment, in the truncated-Wigner semiclassical treatment, and in the full many-body quantum simulations.

• From integrability to chaos: the quantum-classical correspondence in a triple well bosonic model [0.0]
  We investigate the semiclassical limit of a bosonic quantum many-body system exhibiting both integrable and chaotic behavior. The transition from regularity to chaos in classical dynamics is visualized through Poincar'e sections. The study systematically establishes quantum-classical correspondence for a bosonic many-body system with more than two wells.

By exploiting the time-dependent generalized Gibbs ensemble method, we demonstrate that quantum coherence and destructive interference play a crucial role in these systems.

• Chaos in the three-site Bose-Hubbard model -- classical vs quantum [0.0]
  We consider a quantum many-body system - the Bose-Hubbard system on three sites - which is neither strongly chaotic nor integrable. We compare quantum measures of chaos in the quantum system, with classical measures of chaos (Lyapunov exponents) in the corresponding classical system. In contrast to both strongly chaotic and integrable systems, the largest Lyapunov exponent is shown to be a multi-valued function of energy.

• Impact of chaos on precursors of quantum criticality [0.0]
  Excited-state quantum phase transitions (ESQPTs) are critical phenomena that generate singularities in the spectrum of quantum systems. We show that finite-size of ESQPTs shrink as chaos increases due to the disturbance of the system.

• Quantum signatures of chaos in a cavity-QED-based stimulated Raman adiabatic passage [0.0]
  A nonlinear stimulated Raman adiabatic passage (STIRAP) is a fascinating physical process that dynamically explores chaotic and non-chaotic phases. With the aim of extracting quantum signatures of a classically chaotic system, it is shown that an out-of-time-ordered correlator captures chaotic/non-chaotic features of the system. A dynamics through the chaotic phase is associated with spreading of many-body quantum state and an irreversible increase in the number of participating adiabatic eigenstates.

• Emergence of classical behavior in the early universe [68.8204255655161]
  Three notions are often assumed to be essentially equivalent, representing different facets of the same phenomenon. We analyze them in general Friedmann-Lemaitre- Robertson-Walker space-times through the lens of geometric structures on the classical phase space. The analysis shows that: (i) inflation does not play an essential role; classical behavior can emerge much more generally; (ii) the three notions are conceptually distinct; classicality can emerge in one sense but not in another.
