A tape-recorder model extracts sequential environmental modes from a noninteracting integrable bath that irreversibly store local-system records, allowing explicit multi-time decoherent histories whose off-diagonal elements are numerically shown to be exponentially suppressed.

Emergence of non-Markovian Decoherent Histories in Integrable Environment: A "Tape Recorder" Model for Local Quantum Observables
A tape-recorder model extracts sequential environmental modes from a noninteracting integrable bath that irreversibly store local-system records, allowing explicit multi-time decoherent histories whose off-diagonal elements are numerically shown to be exponentially suppressed.
