Item Searching for scalar ultralight dark matter via refractive index changes in fibers(Physical Review D, 2023-10-11) Manley, J.; Stump, R.; Petery, R.; Singh, S.We propose using an optical fiber-based interferometer to search for scalar ultralight dark matter (UDM) with particle mass in the range 10−17−10−13 eV/c2 (10−3−10Hz). Composed of a solid core and a hollow core fiber, the proposed detector would be sensitive to relative oscillations in the fibers’ refractive indices due to scalar UDM-induced modulations in the fine-structure constant α. We predict that, implementing detector arrays or cryogenic cooling, the proposed optical fiber-based scalar UDM search has the potential to reach new regions of the parameter space. Such a search would be particularly well-suited to probe for a solar halo of dark matter with a sensitivity exceeding that of previous dark matter searches over the particle mass range 7×10−17−2×10−14 eV/c2.
