Abstract

We point out that a cold dark matter condensate made of gauge bosons from an extra hidden U(1) sector—dubbed hidden photons—can create a small, oscillating electric density current. Thus, they could also be searched for in the recently proposed LC-circuit setup conceived for axion cold dark matter search by Sikivie, Sullivan and Tanner. We estimate the sensitivity of this setup for hidden-photon cold dark matter and we find it could cover a sizable, so far unexplored parameter space.
