LC Circuits for Direct Detection of Ultralight Dark Matter
ORAL
Abstract
The modification of electrodynamics in the presence of ultralight axion-like dark matter (DM)
is well-known and has been used to realize LC circuit probes of such sub-eV mass-scale
dark matter. Other ultralight bosonic dark matter candidates are possible, and here we
reframe the modification of electrodynamics for the ultralight scalar case.
With this, we can adapt axion search methods to a scalar candidate.
In particular, we show that resonant LC circuit searches for axions can be modified
to detect scalar dark matter particles exploiting the large electric fields
developed for use in neutron EDM experiments. Our proposed experimental set-up can improve upon
previous sensitivity measurements for scalar particles from ``light shining
through a wall'' experiments.
