controls the width of the spectral density. A similar argument for the Markovian limit can also be made for the Ohmic spectral density. Eq. 14 is a seminal result from the early work of Leggett and Garg, et al. , which was derived from performing a normal-mode transformation of the bath while assuming the Markovian limit for the secondary bath. It can also be reached from the more general results in Eq. 11 by directly taking the Markovian limit. The reorganization energy for the effective bath described by J eff (ω) in Eq. 11 is given as 46
