Highlights issues with parameter variation methodology

Questions the validity of the original conclusions

Abstract

A recent manuscript ( arXiv:2002.07488 (2020) ) compares the effect of linear dissipators and squeezing drive on quantum synchronisation. We point at serious mistakes in the validity of the equations they use, the consistency of the ansatz employed, the unregulated fashion in which parameters are varied and the misleading scientific statements made in their manuscript.
