Sub-eV dark photon dark matter is an interesting possible. The creation  mechanism makes the vector bosons' energy spectral density very high,  therefore, the dark electric dipole transition rate in atoms is boosted  if the energy gap between atomic states equals the mass of the vector  bosons. By using the Zeeman effect, the energy gap between atomic states  can be tuned. When the energy gap matches the mass of the cosmic vector  bosons, induced transitions occur and can be registered.
