Ultralight Axial Dark Matter
Anson Hook, Junwu Huang, Kevin Zhou
Ultralight dark matter could be an axial vector field, a simple possibility which motivates new experiments. Couplings to fermions, through an axial vector current or a dark electr…
No cosmological constraints on dark photon dark matter from resonant conversion: Impact of nonlinear plasma dynamics
Anson Hook, Junwu Huang, Mohamad Shalaby
We revisit and invalidate all dark photon dark matter constraints from resonant conversion of dark photons into photons (plasmons) in the early universe. These constraints rely on…
Searching for String Bosenovas with Gravitational Wave Detectors
Dawid Brzeminski, Anson Hook, Junwu Huang +1
We study the phenomenology of string bosenova explosions in vector superradiance clouds around spinning black holes, focusing on the observable consequences in gravitational wave d…
Patchy Screening of the CMB from Dark Photons
Dalila Pîrvu, Junwu Huang, Matthew C. Johnson
We study anisotropic (patchy) screening induced by the resonant conversion of cosmic microwave background (CMB) photons into dark-sector massive vector bosons (dark photons) as the…
Dark photon superradiance: Electrodynamics and multimessenger signals
Nils Siemonsen, Cristina Mondino, Daniel Egana-Ugrinovic +3
We study the electrodynamics of a kinetically mixed dark photon cloud that forms through superradiance around a spinning black hole, and design strategies to search for the resulti…
A Mass for the Dual Photon
Anson Hook, Junwu Huang
We explore a novel IR phase of electromagnetism and place constraints on it. The usual IR modification of electromagnetism, the Higgs phase, involves adding a photon mass for the g…
