Comment on A dark matter interpretation of excesses in multiple direct detection experiments [arXiv:2002.06937]

Abstract

In their recent preprint [arXiv:2002.06937], Kurinsky, Baxter, Kahn, and Krnjaic assume an unphysical ionization yield for plasmon excitations in order to claim a possible dark matter signal. Their proposed signal is not possible based on known physics, but their proposed detection method warrants further investigation.
