We numerically study the possibility of many-body localization transition in a disordered quantum dimer model on the honeycomb lattice. By using the peculiar constraints of this model and state-of-the-art exact diagonalization and time evolution methods, we probe both eigenstates and dynamical properties and conclude on the existence of a localization transition, on the available time and length scales (system sizes of up to N=108 sites). We critically discuss these results and their implications.

在蜂窝晶格上的无序量子二聚体模型中探测多体定位

我们数值研究了蜂窝晶格上无序量子二聚体模型中多体定位转变的可能性。通过使用该模型的特殊约束以及最新的精确对角化和时间演化方法,我们可以探索本征态和动力学特性,并在可用的时间和长度尺度(系统大小)上得出局域化过渡的存在最多N = 108个网站)。我们批判性地讨论了这些结果及其含义。
