受最近的光学晶格实验的启发[J. - y. Choi等人，Science 352，1547（2016）SCIEAS 0036 -807510.1126/science.aaf8834]，我们研究了在二维中存在无序的情况下强相互作用玻色子的动力学。我们表明，Gutzwiller平均场理论（GMFT）捕获的主要实验观察，这是无序和相互作用之间的竞争的结果。我们的研究结果突出了区分玻璃态动力学的困难，这可以通过GMFT捕获，和多体定位，这不能通过GMFT捕获，并表明需要进一步的实验研究这个系统。
Motivated by recent optical lattice experiments [J.-y. Choi et al., Science 352, 1547 (2016)SCIEAS0036-807510.1126/science.aaf8834], we study the dynamics of strongly interacting bosons in the presence of disorder in two dimensions. We show that Gutzwiller mean-field theory (GMFT) captures the main experimental observations, which are a result of the competition between disorder and interactions. Our findings highlight the difficulty in distinguishing glassy dynamics, which can be captured by GMFT, and many-body localization, which cannot be captured by GMFT, and indicate the need for further experimental studies of this system.
