Single arm interferometry to probe the scalar field dark matter
Abstract
We analyze the interaction of photons with a scalar dark matter field ϕ , and we propose to use a single arm interferometer to reveal this interaction and constrain the parameters of the scalar dark matter model. By considering a beam of coherent light and two spatially separated squeezing operations, we show that the interaction of photons with scalar dark matter leads to an observable deviation in the outgoing light state, with respect to free evolution. Therefore the single-arm interferometer may yield a novel revelation method for scalar dark matter.
