Reaffirmed the original results using functional renormalization group

Clarified the theoretical framework and assumptions

Abstract

We respond to the comment arXiv:1809.03931 put forward by Li-Han Chen, Zhen Liu, and Jian-Tin Zheng on our work Kiesel, Platt, and Thomale, Phys. Rev. Lett. 110, 126405 (2013). All misunderstandings and misconceptions communicated in the comment are addressed in light of the status quo of functional renormalization group.
