Query: Universal S-matrix correlations for complex scattering of many-body
  wavepackets: theory, simulation and experiment   We present an in-depth study of the universal correlations of
scattering-matrix entries required in the framework of non-stationary many-body
scattering where the incoming states are localized wavepackets. Contrary to the
stationary case the emergence of universal signatures of chaotic dynamics in
dynamical observables manifests itself in the emergence of universal
correlations of the scattering matrix at different energies. We use a
semiclassical theory based on interfering paths, numerical wave function based
simulations and numerical averaging over random-matrix ensembles to calculate
such correlations and compare with experimental measurements in microwave
graphs, finding excellent agreement. Our calculations show that the
universality of the correlators survives the extreme limit of few open channels
relevant for electron quantum optics, albeit at the price of dealing with
large-cancellation effects requiring the computation of a large class of
semiclassical diagrams.
