Query: Operator growth and eigenstate entanglement in an interacting integrable
  Floquet system   We analyze a simple model of quantum dynamics, which is a discrete-time
deterministic version of the Frederickson-Andersen model. We argue that this
model is integrable, with a quasiparticle description related to the classical
hard-rod gas. Despite the integrability of the model, commutators of physical
operators grow as in generic chaotic models, with a diffusively broadening
front, and local operators obey the eigenstate thermalization hypothesis (ETH).
However, large subsystems violate ETH; as a function of subsystem size,
eigenstate entanglement first increases linearly and then saturates at a scale
that is parametrically smaller than half the system size.
