Light-pulse atom interferometry has evolved into a versatile and powerful tool for high-precision measurements of inertial forces. Whereas this sensitivity relies on the external degree of freedom, the internal structure of atoms gives another degree of freedom that makes them susceptible to relativistic effects [1,2]. In such a framework, the light-matter interaction takes place locally on each branch of the interferometer, making a branch-dependent formalism [3] a convenient and essential tool for the description of atom interferometers. Since the exact diffraction mechanism [4] as well as the specific geometry [3] determine the proper-time difference between the two branches, branch-dependent diffraction will have a similar effect. In our contribution we discuss atom interferometry from a branch-dependent perspective as well as the influence of different internal states and transitions.
