Gravitational Interaction of Ultralight Dark Matter with Interferometers

Understand

Ultralight dark matter exhibits an order-one density fluctuation over the spatial scale of its wavelength.

• These fluctuations gravitationally interact with gravitational wave interferometers, leading to distinctive signals in detectors.
• We investigate the ultralight dark matter-induced effects in the gravitational wave interferometers.
• We perform a systematic computation of the power spectrum of ultralight dark matter in interferometers.
