Description
Ultralight scalar field dark matter (ULDM) provides a compelling alternative to the standard cold dark matter paradigm, exhibiting wave-like behavior on galactic and cosmological scales. After a brief review of ULDM and self-interacting ULDM (SI-ULDM), we discuss how SI-ULDM can alleviate the Hubble and S₈ tensions. We also briefly explore possible connections between the SI-ULDM framework, neutrino mass, and the electroweak scale, suggesting a common origin for these phenomena beyond the Standard Model.
