Reply to the comment on: "Does an atom interferometer test the gravitational redshift at the Compton frequency?"

TL;DR

This paper defends the original claim that atom interferometers do not test the gravitational redshift at the Compton frequency, countering a recent comment that challenged this conclusion.

Contribution

The authors clarify and reaffirm their original analysis, demonstrating that atom interferometric gravimeters are not suitable for testing gravitational redshift at the Compton frequency.

Findings

Original conclusion remains valid

Comment does not alter the main result

Atom interferometers do not test gravitational redshift at the Compton frequency

Abstract

Hohensee, Chu, Peters and M\"uller have submitted a comment (arXiv:1112.6039 [gr-qc]) on our paper "Does an atom interferometer test the gravitational redshift at the Compton frequency?", Classical and Quantum Gravity 28, 145017 (2011), arXiv:1009.2485 [gr-qc]. Here we reply to this comment and show that the main result of our paper, namely that atom interferometric gravimeters do not test the gravitational redshift at the Compton frequency, remains valid.
