Equilibration Dynamics of Strongly Interacting Bosons in 2D Lattices with Disorder. Yan, M., Hui, H., Rigol, M., & Scarola, V., W. Physical Review Letters, 119(7):073002, 8, 2017. Paper Website doi abstract bibtex 7 downloads Motivated by recent optical lattice experiments [Choi et al., arXiv:1604.04178], 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.
