DESCRIPTION:Dr Julian Leonard\, Harvard University\nThe high-energy dynami
 cs of quantum many-body systems are usually governed by their approach tow
 ards thermal equilibrium\, which rapidly simplifies their local behavior t
 o the framework of classical statistical mechanics. A breakdown of this pa
 radigm can occur in the presence of disorder\, where many-body localizatio
 n completely inhibits those thermalization dynamics. Strikingly\, despite 
 their localized nature\, many-body-localized systems are expected to show 
 ongoing coherent dynamics that manifest as a slow buildup of entanglement.
 \n \nIn my talk\, I will present our recent studies on many-body localiza
 tion. We prepare a pure quantum state out of equilibrium\, evolve it unita
 rily under the interacting Aubry-André Hamiltonian\, and perform projecti
 ve measurements in the Fock basis. We observe a number of key properties\,
  such as the mentioned slow buildup of entanglement\, extensive entangleme
 nt of the many-body state\, and a diverging state complexity at the many-b
 ody localization transition.\n
