Entanglement Propagation in Thermalization of an Isolated Quantum System
Entanglement Propagation in Thermalization of an Isolated Quantum System
We study dynamics of entanglement in the thermalization process of an isolated quantum many-body system. We propose a simple setup for measuring the propagation speed of entanglement entropy (EE) in numerical simulations and apply it to the integrable/non-integrable spin models in 1D — the transverse Ising (TI) model, the chaotic …
