Description
I will discuss some possible ways of looking for sub-MeV dark matter using the emission of collective excitations in different media. In particular, I will discuss the possibility of probing spin-independent interactions using superfluid He-4, and spin-dependent ones using antiferromagnets (specifically, NiO and MnF2).
In doing that, I will employ a new theoretical tool, very familiar to high energy physicists, but just recently employed in the phenomenological study of phases of matter: effective field theories for the collective excitations of the material.
