Decoherence of Histories: Chaotic Versus Integrable Systems

Author(s): Jiaozi Wang and Philipp Strasberg We study the emergence of decoherent histories in isolated systems based on exact numerical integration of the Schrödinger equation for a Heisenberg chain. We reveal that the nature of the system, which we switch from (i) chaotic to (ii) interacting integrable to (iii) noninteracting integrable, str… [Phys. Rev.
