Reply to Comment on "Unconventional s-wave superconductivity in Fe(Se,Te)"

TL;DR

This paper defends the interpretation of spectroscopic peaks in Fe(Se,Te) as quasiparticle interference signals rather than Bragg peaks, clarifying the nature of observed features.

Contribution

It provides evidence that the spectroscopic peaks are due to QPI, countering claims that they are Bragg peaks from lattice or surface effects.

Findings

Peaks are too broad to be Bragg peaks

Spectroscopic peaks are consistent with QPI signals

Clarifies the origin of features in Fe(Se,Te) spectra

Abstract

Mazin and Singh comment that the peaks in the Fourier-transformed spectroscopic maps of Fe(Se,Te) are not related to the quasi-particle-interference (QPI) but may be Bragg peaks associated with chalcogen lattice and possible surface reconstruction which would be triggered by surface-induced spin-density wave. We show that the peaks are too broad to be assigned as Bragg peaks and are consistent with QPI.
