SQUID-based Resonant Detection of Axion Dark Matter

High Energy Physics - Phenomenology 2016-05-30 v1

Abstract

A new method for searching for Dark Matter axions is proposed. It is shown that a two-contact SQUID can detect oscillating magnetic perturbations induced by the axions in a strong inhomogeneous magnetic field. A resonant signal is a steplike response in the SQUID current-voltage characteristic at a voltage corresponding to the axion mass with a height depending on the axion energy density near the Earth. The proposed experimental technique appears to be sensitive to the axions with masses ma104m_a\lesssim 10^{-4} eV, which is well-motivated by current researches both in cosmology and in particle physics.
