Toy model for anomalous transport and Griffiths effects near the many-body localization transition
Toy model for anomalous transport and Griffiths effects near the many-body localization transition
We introduce and study a toy model for anomalous transport and Griffiths effects in one-dimensional (1D) quantum disordered isolated systems near the many-body localization (MBL) transition. The model is constituted by a collection of 1D tight-binding chains with on-site random energies, locally coupled to a weak perturbation, corresponding to a …
