Contribution

It provides a counter-argument to criticisms of the original work, clarifying the validity of their theoretical approach in quantum membrane thermodynamics.

Findings

Counter-arguments to criticisms of UV regulation method

Clarification of theoretical assumptions in quantum membrane thermodynamics

Reaffirmation of original results' validity

Abstract

In this note, we reply to the comment made by E.I.Kats and V.V.Lebedev [arXiv:1407.4298] on our recent work "Thermodynamics of quantum crystalline membranes" [Phys. Rev. B 89, 224307 (2014)]. Kats and Lebedev question the validity of the calculation presented in our work, in particular on the use of a Debye momentum as a ultra-violet regulator for the theory. We address and counter argue the criticisms made by Kats and Lebedev to our work.
