摘要:

受最近的光晶格实验的启发[J. - y. Choi等人,Science 352,1547(2016)],我们研究了在二维无序存在下强相互作用玻色子的动力学。我们表明,Gutzwiller平均场论(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,这可以被捕获的GMFT,和多体局域化,这不能被捕获的GMFT,并表明需要进一步的实验研究这个系统。

英文摘要:

Motivated by recent optical lattice experiments [J.-y. Choi et al., Science 352, 1547 (2016)], 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.
