Direct detection experiments for dark matter are increasingly ruling out large parameter spaces. However, light dark matter models with particle masses < GeV are still largely unconstrained. Here we examine a proposal to use atom interferometers to detect a light dark matter subcomponent at sub-GeV masses. We describe the decoherence and phase shifts caused by dark matter scattering off of one "arm" of an atom interferometer using a generalized dark matter direct detection framework. This allows us to consider multiple channels: nuclear recoils, hidden photon processes, and axion interactions. We apply this framework to several proposed atom interferometer experiments. Because atom interferometers are sensitive to extremely low momentum deposition and their coherent atoms give them a boost in sensitivity, these experiments will be highly competitive and complementary to other direct detection methods. In particular, atom interferometers are uniquely able to probe a dark matter sub-component with mχ ≲ 10 keV. We find that, for a mediator mass m_ϕ = 10⁻¹⁰ mχ, future atom interferometers could close a gap in the existing constraints on nuclear recoils down to σ̅ₙ ∼ 10⁻⁵⁰ cm² for mχ∼10⁻⁵−10⁻¹ MeV dark matter masses.
