Fig. 8

Growth of entanglement entropy from the \(| \,{\mbox{vac}}\,\left.\right\rangle\) initial state for system size N = 50 at coupling strength J/w = 3, obtained via matrix product state simulations (see Methods for details). The data is averaged over 1000 background charge sectors, with the uncertainty in the mean represented by the shading. The dashed lines indicate different types of fits summarized in the legend: a logarithmic fit, and a power-law fit with exponent γ = (6.87 ± 0.10) × 10−2.
