Article Synopsis
- A high-precision test of the spin- and velocity-dependent (SVD) interaction between spin-polarized protons and unpolarized nucleons is conducted using a Bragg atom interferometer with ^{87}Rb atoms.
- The experiment enhances the precision of free fall measurements to 9.2×10^{-9}, significantly improving on earlier polarized atom experiments.
- It also provides a new constraint on the SVD interaction coupling, indicating greater sensitivity and opening new avenues for studying physics with polarized-atom interferometers.
We present a matter wave gyroscope with a Sagnac area of 5.92 cm, achieving a short-term sensitivity of 167 nrad/s/Hz. The atom interferometry gyroscope is driven by a π/2 - π - π - π/2 Raman pulse sequence based on an atom fountain with a parabolic trajectory.
