Abstract

This paper presents a laboratory-based, blinded test of the gravitational redshift using an array of five atomic ensembles. The experiment measured a fractional frequency gradient consistent with the expected redshift gradient, demonstrating the potential of differential clock comparisons for applications like geodesy and gravitational wave detection.
