Previously proposed dark matter absorption searches using crystalline targets face a fundamental limitation: momentum conservation in a perfect crystal restricts absorption to occur only when the dark matter mass is resonant with one of a small number of optical phonon frequencies. For a dark matter mass hypothesis that doesn't coincide with these narrow resonances, absorption must proceed...
