Title Many-Body Localization in 2D and constrained models
Abstract Many-body localization is a way to break ergodicity, thermalization and transport in disordered interacting quantum systems.The existence of a many-body localization transition in 2D systems is an open question that is being addressed experimentally, theoretically and numerically. In this talk, I will show some recent numerical results for a model whose features make it especially accessible to exact diagonalization. We numerically study the possibility of many-body localization transition in a constrained system: 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 large two-dimensional systems of up to N=108 sites.
