Axion Dark Matter Search with Interferometric Gravitational Wave Detectors
Axion dark matter differentiates the phase velocities of the
circular-polarized photons. In this Letter, a scheme to measure the phase
difference by using a linear optical cavity is proposed. If the scheme is
applied to the Fabry-P\'erot arm of Advanced LIGO-like (Cosmic-Explorer-like)
gravitational wave detector, the potential sensitivity to the axion-photon
coupling constant, , reaches GeV GeV at the axion mass
eV ( eV) and remains at around
this sensitivity for 3 orders of magnitude in mass. Furthermore, its
sensitivity has a sharp peak reaching
GeV GeV at eV
( eV). This sensitivity can be achieved without loosing
any sensitivity to gravitational waves.Comment: 7 pages, 2 figure
