We investigate the localization in a one-dimensional modified Peierls model with a non-adiabatic dynamic method. Different 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 effect of many-body localization is not observed. The role of disorder presented at finite temperature is discussed as well. The electrons diffuse in a classical manner. Benefitting from the indication of OTOC, it is found that the Anderson localization becomes dominant instead of dynamic localization as observed in disorder-free lattices.

非绝热过程中的无序动态定位：纠缠熵和 OTOC

我们使用非绝热动力学方法研究一维修正 Peierls 模型中的定位。与极化子场景不同，这里的定位源于无序晶格中广泛的守恒局部量。纠缠熵和无序相关器 (OTOC) 都显示了动态生成定位的振荡特征。虽然电子之间的强相互作用可能会抑制定域的动力学特征，但未观察到多体定域的影响。还讨论了在有限温度下出现的无序的作用。电子以经典方式扩散。受益于 OTOC 的指示，发现安德森定位变得占主导地位，而不是在无序晶格中观察到的动态定位。
