Abstract

We compare expressions for the atom interferometer phase obtained using the path integral approach and the approach based on the density matrix equation in the Wigner representation. The power series of these expressions over the Planck constant, truncated to the ℏ ² term, coincide. This coincidence is achieved only after the Q-term is included.
