Key Details

Self-induced decoherence occurs in isolated quantum systems due to internal interactions

It causes the system to lose quantum coherence over time in its coarse-grained representation

This is simulated numerically in the few-body Bose-Hubbard model

The main factors enabling this are eigenstate deformations and energy shifts

The energy shifts play the biggest role in long-term decoherence

Self-induced loss of quantum coherence in isolated interacting systems

This paper provides numerical evidence and analysis of self-induced decoherence, which is the loss of quantum coherence in the coarse-grained representation of an isolated interacting quantum system over time. The authors simulate the few-body Bose-Hubbard model and find purity decays, indicating decoherence, even without an external environment. They determine the predominant causes are eigenstate deformations and energy shifts relative to the non-interacting system.
