Query: Stabilizing coherence with nested environments: a numerical study using
  kicked Ising models   We study a tripartite system of coupled spins, where a first set of one or
two spins is our central system which is coupled to another set considered, the
near environment, in turn coupled to the third set, the far environment. The
dynamics considered are those of a generalized kicked spin chain in the regime
of quantum chaotic dynamics. This allows to test recent results that suggest
that the presence of a far environment, coupled to the near environment, slows
decoherence of the central system. After an extensive numerical study, we
confirm previous results for extreme values and special cases. In particular,
under a wide variety of circumstances an increasingly large coupling between
near and far environment, slows decoherence, as measured by purity, and
protects internal entanglement.
