The reaction-coordinate mapping is a useful technique to study complex quantum dissipative dynamics into structured environments. In essence, it aims to mimic the original problem by means of an "augmented system," which includes a suitably chosen collective environmental coordinate-the "reaction coordinate." This composite then couples to a simpler "residual reservoir" with short-lived correlations. If, in addition, the residual coupling is weak, a simple quantum master equation can be…
