The simulation of matter-wave light-pulse interaction is crucial for designing and understanding atom interferometry (AI) experiments. However, the usual approach of solving the associated system of ordinary differential equations is limited by a quadratic scaling with the number of coupling states. Here, the universal atom interferometer simulator (UATIS) [1] overcomes this limitation with log-linear scaling while solving the problem of atom-light diffraction in the elastic case for all regimes. By interpreting a light-pulse beam as an external potential, UATIS achieves high numerical accuracy while maintaining great flexibility. We propose intuitive methods for assembling various atom-light interactions into AI sequences. We expect UATIS to lead to a straightforward modelling of experiments and to be promoted to a widely used tool.
