Multifractality and its role in anomalous transport in the disordered XXZ spin-chain
Multifractality and its role in anomalous transport in the disordered XXZ spin-chain
The disordered XXZ model is a prototype model of the many-body localization transition (MBL). Despite numerous studies of this model, the available numerical evidence of multifractality of its eigenstates is not very conclusive due severe finite size effects. Moreover it is not clear if similarly to the case of single-particle …
