DESCRIPTION:Speaker: Paolo P. Mazza\nhosted by Maksym Serbyn\nAbstract: A r
 ecent experiment performed in a 51-Rydberg atoms chain with nearest neighb
 ours strong interactions (blockade regime)\, observed long-lived oscillati
 ons in the expectation value of local observables quenching from a Neel-or
 dered initial state. This fact seems to violate the common belief accordin
 g to which the initial state should rapidly thermalize. In this talk I wil
 l present a new approach to tackle this problem\, connecting it to epitome
  phenomena in high-energy physics. In particular\, I will show how the Ham
 iltonian describing the atom chain can be exactly mapped to a U(1) lattice
  gauge theory\, namely S=1/2-QLM. This fact enables us to interpret the ob
 served long-lived oscillations as slow string dynamics and\, furthermore\,
  shows the possibility of performing large scale quantum simulations in la
 ttice gauge theories with the state-of-the-art technology.
