Query: Quench dynamics of quasi-periodic systems exhibiting Rabi oscillations
  of two-level integrals of motion   The elusive nature of localized integrals of motion (or l-bits) in disordered
quantum systems lies at the core of some of their most prominent features, i.e.
emergent integrability and lack of thermalization. Here, we study the quench
dynamics of a one-dimensional model of spinless interacting fermions in a
quasi-periodic potential with a localization-delocalization transition.
Starting from an unentangled initial state, we show that in the strong disorder
regime an important subset of the $l$-bits can be explicitly identified with
strongly localized two-level systems, associated with particles confined on two
lattice sites. The existence of such subsystems forming an ensemble of nearly
free l-bits is found to dominate the short-time dynamics of experimentally
relevant quantities, such as the Loschmidt echo and the particle imbalance. We
investigate the importance of the choice of the initial state by developing a
second quench protocol, starting from the ground-state of the model at
different initial disorder strengths and monitoring the quench dynamics close
to the delicate ETH-MBL transition regime.
