title: Noisy metamolecule: strong narrowing of fluorescence line: comment.
abstract: We comment on the recent Letter by Andrianov et al. [Opt. Lett.40, 3536 (2015)OPLEDP0146-959210.1364/OL.40.003536], in which they study a strongly dissipative driven bosonic mode strongly coupled to a two-level system using the quantum Monte Carlo simulations. We recalculate their quantities via sparse numerical solvers and find that their results for larger drives are incorrect, most likely due to insufficient Monte Carlo sampling in the presence of an emergent long time scale. These findings call for a corrected interpretation of the physical behavior of the studied model.
