Numerical Backreaction and Finite-Time Energy Transfer in Post-Recombination Magnetogenesis from Ultralight Dark Matter
Aviv David, Robert Brandenberger
We study gauge-field production in a post-recombination magnetogenesis scenario driven by an ultralight pseudoscalar dark matter field coupled to electromagnetism. Previous ana…
Secondary Production of Photons from ALP Dark Matter interacting with a Cosmological Magnetic Field
Abdias Aires, Robert Brandenberger, Ashu Kushwaha
Under the assumption that dark matter is a coherently oscillating pseudoscalar field coupled to electromagnetism by the usual Chern-Simons term, we study the production of secondar…
Indirect Parametric Resonance of the Electromagnetic Field Driven by an Oscillating SU(2) Dark Matter Condensate
Tatsuya Daniel, Vahid Kamali, Robert Brandenberger
We study a local patch of an axion-like dark sector in Minkowski spacetime, containing an initially homogeneous and isotropic non-Abelian condensate, and a real pseudoscala…
ALP Dark Matter, Cosmological Magnetic Fields and the Direct Collapse Black Hole Formation Scenario
Ashu Kushwaha, Robert Brandenberger
Assuming that dark matter is an ultralight pseudoscalar particle which couples to electromagnetism like an axion (an ALP), we demonstrate that the coupling of the cosmological magn…
Parametric Resonance and Backreaction Effects in Magnetogenesis from Ultralight Dark Matter
Nirmalya Brahma, Robert Brandenberger
We take a more detailed look at the recently proposed magnetogenesis mechanism triggered by ultralight dark matter coupled to electromagnetism. The proposed mechanism made use of a…
Cosmic Vortons and Particle Physics Constraints
R. Brandenberger, B. Carter, A. -C. Davis +1
We investigate the cosmological consequences of particle physics theories that admit stable loops of superconducting cosmic string - {\it vortons}. General symmetry breaking scheme…
Particle Physics Models, Topological Defects and Electroweak Baryogenesis
M. Trodden, A-C. Davis, R. Brandenberger
We demonstrate the viability of electroweak baryogenesis scenarios in which the necessary departure from equilibrium is realized by the evolution of a network of topological defect…
Local and Nonlocal Defect-Mediated Electroweak Baryogenesis
Robert Brandenberger, Anne-Christine Davis, Tomislav Prokopec +1
We consider the effects of particle transport in the topological defect-mediated electroweak baryogenesis scenarios of Ref. 1. We analyze the cases of both thin and thick defects a…
Electroweak Baryogenesis with Topological Defects
A. C. Davis, R. Brandenberger, M. Trodden
Electroweak baryogenesis has become a topic of much recent activity [1]. Here we discuss a new scenario which has the advantage of being insensitive to the order of the electroweak…
Formation of Topological Defects at First Order Phase Transitions
Mark Hindmarsh, Robert Brandenberger, Anne-Christine Davies
We analyze the evolution of scalar and gauge fields during first order phase transitions and show how the Kibble mechanism for the formation of topological defects emerges from the…
