    "abstract": "In this work we develop a numerical framework to investigate the\nrenormalization of the non-Markovian dynamics of an open quantum system to\nwhich dynamical decoupling is applied. We utilize a non-Markovian master\nequation which is derived from the non-Markovian quantum trajectories\nformalism. It contains incoherent Markovian dynamics and coherent Schr\\\"odinger\ndynamics as its limiting cases and is capable of capture the transition between\nthem. We have performed comprehensive simulations for the cases in which the\nsystem is either driven by the Ornstein-Uhlenbeck noise or or is described by\nthe spin-boson model. The renormalized dynamics under bang-bang control and\ncontinuous dynamical decoupling are simulated. Our results indicate that the\nrenormalization of the non-Markovian dynamics depends crucially on the spectral\ndensity of the environment and the envelop of the decoupling pulses. The\nframework developed in this work hence provides an unified approach to\ninvestigate the efficiency of realistic decoupling pulses. This work also opens\na way to further optimize the decoupling via pulse shaping.",
