Query: Exact Non-Markovian master equation for the Spin-Boson and
  Jaynes-Cummings models   We provide the exact non-Markovian master equation for a two-level system
interacting with a thermal bosonic bath, and we write the solution of such a
master equation in terms of the Bloch vector. We show that previous
approximated results are particular limits of our exact master equation. We
generalize these results to more complex systems involving an arbitrary number
of two-level systems coupled to different thermal baths, providing the exact
master equations also for these systems. As an example of this general case we
derive the master equation for the Jaynes-Cummings model.
