Emergence of chaos with exceptional points in reset-driven Floquet dynamics
The research investigates quantum channels generated by periodically resetting a many-body system evolving under an interacting Hamiltonian. Tuning a chaos parameter causes an exceptional point (EP) transition, moving the channel from a symmetry-constrained ergodic regime to a fully chaotic one. This spectral reorganization distinguishes dynamical regimes and links leading eigenvalues to measurable quantities like quantum mutual information.
