Entanglement dynamics in critical random quantum Ising chain with perturbations
arXiv:1611.04727 · doi:10.1016/j.aop.2017.02.018
Abstract
We simulate the entanglement dynamics in a critical random quantum Ising chain with generic perturbations using the time-evolving block decimation algorithm. Starting from a product state, we observe super-logarithmic growth of entanglement entropy with time. The numerical result is consistent with the analytical prediction of Vosk and Altman using a real-space renormalization group technique.
