Abstract
Amorim et al. [Phys. Rev. B 89, 224307 (2014)] reported the theoretical investigation of quantum crystalline membranes. In this Comment we dismiss the validity of their calculations based on a “natural” estimation of the ultraviolet divergent contributions into correlation functions. We claim that such calculations give qualitatively the wrong results.
