Many-body delocalization dynamics in long Aubry-André quasiperiodic chains
Many-body delocalization dynamics in long Aubry-André quasiperiodic chains
We study quench dynamics in an interacting spin chain with a quasi-periodic on-site field, known as the interacting Aubry-Andr\'e model of many-body localization. Using the time-dependent variational principle, we assess the late-time behavior for chains up to $L = 50$. We find that the choice of periodicity $\Phi$ of the …
