Origin of the slow growth of entanglement entropy in long-range interacting spin systems
Alessio Lerose, Silvia Pappalardi
Abstract
The authors provide a comprehensive theory for quantum entanglement, that accounts for previous puzzling numerical results and agrees with new simulations. The paper shows how the standard quasiparticle contribution is suppressed and entanglement entropy growth is dominated by collective squeezing, accessible in experiments.
