In recent years, several atom interferometers have been suggested [1] and realized [2,3], where the phase shift contains a contribution that scales as T3 in contrast to conventional atom interferometers with a scaling of T2. Here T denotes the total interferometer time. We review and compare these interferometers by applying a representation-free formalism [4] and obtain the cubic phase shift as a result of a piecewise constant, but branch-dependent acceleration of the atoms. Moreover, we relate this phase to the area in space-time enclosed by the two branches of the interferometer.
