Gauge preheating with full general relativity
Peter Adshead, John T. Giblin, Ryn Grutkoski +1
We study gauge preheating following pseudoscalar-driven inflation in full general relativity. We implement the Baumgarte-Shapiro-Shibata-Nakamura (BSSN) scheme to solve the full no…
Detectable and defect-free dark photon dark matter
David Cyncynates, Zachary J. Weiner
Ultralight dark photons are compelling dark matter candidates, but their allowed kinetic mixing with the Standard Model photon is severely constrained by requiring that the dark ph…
Dark photon dark matter from an oscillating dilaton
Peter Adshead, Kaloian D. Lozanov, Zachary J. Weiner
We present a mechanism for generating ultralight dark photon dark matter in the early Universe via a dilatonlike scalar field coupled to the dark photon's kinetic term. Energy is i…
