“Entanglement Entropy and Initial State Coherence Impact Thermalization in Quantum Ising and Many-Body Localized XXZ Models during Interaction Quenching”

https://pubmed.ncbi.nlm.nih.gov/38115417

This study investigates the dynamics of a sunburst quantum Ising model during interaction quenching, finding that entanglement entropy and initial state coherence significantly impact thermalization in both integrable and chaotic systems, with similar results observed when replacing the Ising ring with a many-body localized XXZ model.
