Disorder-free dynamic localization in non-adiabatic processes: entanglement entropy and OTOC.
2020
We investigate the localization in a one-dimensional modified Peierls model with a non-adiabatic dynamic method. Di ff erent from the polaron scenario, here the localization stems from extensive conserved local quantities in the disorder-free lattice. Both the entanglement entropy and out-of-time-ordered correlator (OTOC) show the oscillating feature of dynamically generated localization. Although the strong interaction between electrons may suppress the dynamical features of the localization, but the e ff ect of many-body localization is not observed. The role of disorder presented at fi nite temperature is discussed as well. The electrons di ff use in a classical manner. Bene fi tting from the indication of OTOC, it is found that the Anderson localization becomes dominant instead of dynamic localization as observed in disorder-free lattices.
