Query: Time-dependent method for many-body problems and its application to
  nuclear resonant systems   The decay process of the schematic one-dimensional three-body system is
considered. A time-dependent approach is used in combination with a
one-dimensional three-body model, which is composed of a heavier core nucleus
and two nucleons, with the aim of describing its evolution in two-nucleon
emission. The process is calculated from the initial state, in which the three
ingredient particles are confined. In this process, two different types of
emission can be found: the earlier process includes the emission of spatially
correlated two-nucleon pair, like a dinucleon, whereas, at a subsequent time,
all the particles are separated from each other. The time-dependent method can
be a suitable option to investigate the meta-stable and/or open-quantum
systems, where the complicated many-body dynamics should necessarily be taken
into account.
