Abstract We revisit the calculation of bosonic dark matter absorption via electronic excitations. Working in an effective field theory framework and consistently taking into account in-medium effects, we clarify the relation between dark matter and photon absorption. As is well-known, for vector (dark photon) and pseudoscalar (axion-like particle) dark matter, the absorption rates can be simply related to the target material’s optical properties. However, this is not the case for scalar dark…

We show that the rate for dark-matter-electron scattering in an arbitrary material is determined by an experimentally measurable quantity, the complex dielectric function, for any dark matter

Atomic Ionization by Scalar Dark Matter and Solar Scalars.
It is argued that the Xenon1T excess can be explained by the emission of scalars from the Sun, and direct limits on scalar DM for the ∼1-10  keV mass range are established.
Detection of sub-MeV dark matter with three-dimensional Dirac materials
We propose the use of three-dimensional Dirac materials as targets for direct detection of sub-MeV dark matter. Dirac materials are characterized by a linear dispersion for low-energy electronic
