Abstract
We present a correction to parts of Fig. 5, Fig. 6 and Fig. 7, relating to the Purcell factors and Lamb shifts, due to an incorrect renormalization used in our custom Fortran code. The resulting corrections to some of the Q-factors are large, but do not affect the conclusions of the original manuscript.

We have discovered that a subroutine used to produce some of the plots in the original manuscript contained a transcription error. The renormalization factor used for the modes contributing to the scattering Green’s function was missing a square root, which weakly affects the associated Purcell factors and Lamb shifts, predominantly at shorter wavelengths. The resulting correction to some of the the Q-factor values is larger – they are comparable to those observed in nanolasers, not higher as originally stated – but applications to nanolasing remain possible. All conclusions discussed in the manuscript remain unchanged by this correction. The data for the two particle case was unaffected. The corrected figures are presented here, and the corrected Q-factors are given in the caption for Fig. 1.
