Venue: 
INI Seminar Room 1
Abstract: 
We consider the evolution from a state with area-law entanglement by a gapless quantum hamiltonian. Do sub-systems thermalize? How fast does the entanglement spread? In a finite system, are there quantum revivals? We attempt to answer these questions in simple solvable field theory models.
