  bibo_abstract:
  - Kapitza-Dirac scattering, the diffraction of matter waves from a standing light
    field, is widely utilized in ultracold gases, but its behavior in the strongly
    interacting regime is an open question. Here, we develop a numerically exact two-body
    description of Kapitza-Dirac scattering for two contact-interacting atoms in a
    one-dimensional harmonic trap subjected to a pulsed optical lattice, enabling
    us to obtain the numerically exact dynamics. We map how interaction strength,
    lattice depth, lattice wave number, and pulse duration reshape the diffraction
    pattern, leading to an interaction-dependent population redistribution in real
    and momentum space. By comparing the exact dynamics to an impulsive sudden-approximation
    description, we delineate the parameter regimes where it remains accurate and
    those, notably at strong attraction and small lattice wave number, where it fails.
    Our results provide a controlled few-body benchmark for interacting Kapitza-Dirac
    scattering and quantitative guidance for Kapitza-Dirac-based probes of ultracold
    atomic systems.@eng
