Query: Amplification and suppression of system-bath correlation effects in an
  open many-body system   Understanding the rich dynamics of open quantum systems is of fundamental
interest to quantum control and quantum information processing. By considering
an open system of many identical two-level atoms interacting with a common
bath, we show that effects of system-bath correlations are amplified in a
many-body system via the generation of a short time scale inversely
proportional to the number of atoms. Effects of system-bath correlations are
therefore considerable even when each individual atom interacts with the bath
weakly. We further show that correlation-induced dynamical effects may still be
suppressed via the dynamical decoupling approach, but they present a challenge
for quantum state protection as the number of atom increases.
