      "value": "We present a first calculation of the rate for plasmon production in semiconductors from nuclei recoiling against dark matter. The process is analogous to bremsstrahlung of transverse photon modes, but with a longitudinal plasmon mode emitted instead. For dark matter in the 10 MeV\u20141 GeV mass range, we find that the plasmon bremsstrahlung rate is 4\u20135 orders of magnitude smaller than that for elastic scattering, but 4\u20135 orders of magnitude larger than the transverse bremsstrahlung rate. Because the plasmon can decay into electronic excitations and has characteristic energy given by the plasma frequency <math><msub><mi>\u03c9</mi><mi>p</mi></msub></math>, with <math><msub><mi>\u03c9</mi><mi>p</mi></msub><mo>\u2248</mo><mn>16</mn><mtext> </mtext><mtext> </mtext><mi>eV</mi></math> in Si crystals, plasmon production provides a new signature and method to detect nuclear recoils from sub-GeV dark matter."
