A Time-Varying Fine Structure Constant from Naturally Ultralight Dark Matter
Dawid Brzeminski, Zackaria Chacko, Abhish Dev +1
We present a class of models in which the coupling of the photon to an ultralight scalar field that has a time-dependent vacuum expectation value causes the fine structure constant…
Signatures of Ultralight Dark Matter in Neutrino Oscillation Experiments
Abhish Dev, Pedro A. N. Machado, Pablo Martínez-Miravé
We study how neutrino oscillations could probe the existence of ultralight bosonic dark matter. Three distinct signatures on neutrino oscillations are identified, depending on the…
Determining the Neutrino Lifetime from Cosmology
Zackaria Chacko, Abhish Dev, Peizhi Du +2
We explore the cosmological signals of theories in which the neutrinos decay into invisible dark radiation after becoming non-relativistic. We show that in this scenario, near-futu…
