Query: Effect of inter-particle interaction in a free oscillation atomic
  interferometer   We investigate the dynamics of two interacting bosons repeatedly scattering
off a beam-splitter in a free oscillation atom interferometer. Using the
inter-particle scattering length and the beam splitter probabilites as our
control parameters, we show that even in a simple setup like this a wide range
of strongly correlated quantum states can be created. This in particular
includes the NOON state, which maximizes the quantum Fisher information and is
a foremost state in quantum metrology.
