Abstract

The optical lattice clocks were proved to be a powerful tool for precision measurement, like measuring the gravitational redshift at tiny gravity potential difference and monitoring the crustal deformations with ultrahigh accuracy. The Floquet optical lattice clock utilizes a time periodical acoustic wave acting on the optical lattice potential. Those atoms trapped in the lattice site will be compelled to move slightly with the modulated potential. These micromotions generate a series of Floquet quasi-energies which the atomic spectra would present for us. In virtue of Floquet engineering optical lattice theoretical model, the periodic acoustic wave signal acting on the lattice potential could be extracted. In this paper, we propose a novel way for acoustic sensing based on a ⁸⁷Sr Floquet optical lattice clock. It may assist the traditional acoustic sensing technology based on fiber in achieving higher signal-noise ratio and accuracy. From the clockmaker's point of view, it may help us monitoring the environmental acoustic noise caused by vibrations and calibrate in time, especially when the optical clock operating in a movable carrier both on earth and space, what is even more important.
