AB We study holographically the out of equilibrium dynamics of a finite size closedquantum system in 2+1 dimensions, modelled by the collapse of a shell of a massless scalarfield in AdS4. In global coordinates there exists a variety of evolutions towards final blackhole formation which we relate with different patterns of relaxation in the dual field theory.For large scalar initial data rapid thermalization is achieved as a priori expected. Interestingphenomena appear for small enough amplitudes. Such shells do not generate a black holeby direct collapse, but quite generically, an apparent horizon emerges after enough bouncesoff the AdS boundary. We relate this bulk evolution with relaxation processes at strongcoupling which delay in reaching an ergodic stage. Besides the dynamics of bulk fields, wemonitor the entanglement entropy, finding that it oscillates quasi-periodically before finalequilibration. The radial position of the travelling shell is brought in correspondence withthe evolution of the pattern of entanglement in the dual field theory. We propose, thereafter,that the observed oscillations are the dual counterpart of the quantum revivals studied inthe literature. The entanglement entropy is not only able to portrait the streaming ofentangled excitations, but it is also a useful probe of interaction effects
