Many-body localization (MBL), the disorder-induced localization of interacting particles, signals a breakdown of conventional thermodynamics, because MBL systems do not thermalize and show nonergodic time evolution. This opens the door to observe quantum effects over unprecedented timescales. We experimentally observed this nonergodic evolution for interacting fermions in a one-dimensional quasirandom optical lattice and identified the MBL transition through the relaxation dynamics of an initially prepared charge density wave. In addition we studied the effects of coupling several localized systems, which highlights the crucial differences between MBL and Anderson localization of non-interacting atoms.
