JAVIER MAS SOLE' Universidad de Santiago de Compostela: Quantum revival is a feature present in particular closed quantum systems whereby the thermalization is apparent and the initial nonequilibrium state is rebuilt periodically after some time. If present in strongly coupled systems, it should show up as a periodic in time solution in the holographically dual model. We argue that this is indeed the case by analyzing the entanglement entropy of a simple system consisting of a massless scalar collapsing in AdS.
