From: Breakdown of thermalization in spin chains with single-ion anisotropy
Imbalance as a function of time for the stark many-body localization (for increasing \(h_0\) and \(D=0)\) [panels (a)-(d)] and for \(h_0=0\) and increasing D [panels (f)-(h)]. Different curves corresponds to different values of \(\theta\) (see legend). The system consists of \(L=12\) spins and the initial state corresponds to an island of of spins with \(S^z_j=3/2\) in the middle of the chain, while all other have \(S^z_j=-3/2\).
