TDVP time evolution with insufficient bond dimension spuriously overestimates delocalization and entanglement in the MBL crossover, and correcting this lowers the estimated critical disorder to Wc = 4.2 ± 0.3.
We also analyse this issue in this work, but first we com- pare the performance of tDMRG and TDVP in systems close to localized regime

Time dynamics with matrix product states: Many-body localization transition of large systems revisited
TDVP time evolution with insufficient bond dimension spuriously overestimates delocalization and entanglement in the MBL crossover, and correcting this lowers the estimated critical disorder to Wc = 4.2 ± 0.3.
