TL;DR

This paper demonstrates how tune-out wavelength shifts in a potassium atom interferometer can be utilized to develop a sensitive gyroscope that detects rotation rates through light-induced phase shifts.

Contribution

It introduces a novel approach to using tune-out wavelength shifts in atom interferometers for rotation sensing, expanding the capabilities of quantum sensors.

Findings

Observed tune-out wavelength shifts up to 213 pm

Shifts are sensitive to laboratory rotation rates

Potential for developing atom interferometer gyroscopes

Abstract

Tune-out wavelengths measured with an atom interferometer are sensitive to laboratory rotation rates because of the Sagnac effect, vector polarizability, and dispersion compensation. We observed shifts in measured tune-out wavelengths as large as 213 pm with a potassium atom beam interferometer, and we explore how these shifts can be used for an atom interferometer gyroscope.
