Quantum Chaos and Entanglement Dynamics

Quantum chaos and entanglement are related but distinct aspects of quantum dynamics. We investigate spectral statistics and out-of-time-order correlators in Rabi-type models, examining the roles of symmetry and integrability and the limits of different chaos diagnostics.

A complementary strand studies entanglement structure and state preparation in coupled qubit-oscillator systems. We explore how interactions, detuning, and parameter ramps redistribute quantum correlations and enable controlled preparation of entangled states.

Our 2026 preprint on tripartite quantum Rabi models studies static entanglement structure and adiabatic Bell-state preparation. It is listed as a preprint, separately from peer-reviewed journal publications. Current projects also explore asymmetric and mixed-coupling extensions.
