Super-horizon resonant magnetogenesis during inflation

Kavli Affiliate: Misao Sasaki | First 5 Authors: Misao Sasaki, Valeri Vardanyan, Vicharit Yingcharoenrat, , | Summary: We propose a novel mechanism for significantly enhancing the amplitude of primordial electromagnetic fields during inflation. Similar to existing proposals, our idea is based on parametric resonance effects due to conformal-symmetry-breaking coupling of the gauge field and the […]

Freezing In Vector Dark Matter Through Magnetic Dipole Interactions

Kavli Affiliate: Gordan Krnjaic | First 5 Authors: Gordan Krnjaic, Duncan Rocha, Anastasia Sokolenko, , | Summary: We study a simple model of vector dark matter that couples to Standard Model particles via magnetic dipole interactions. In this scenario, the cosmological abundance arises through the freeze-in mechanism and depends on the dipole coupling, the vector […]

Testing the mean field theory of scalar field dark matter

Kavli Affiliate: Tom Abel | First 5 Authors: Andrew Eberhardt, Alvaro Zamora, Michael Kopp, Tom Abel, | Summary: Scalar field dark matter offers an interesting alternative to the traditional WIMP dark matter picture. Astrophysical and cosmological simulations are useful to constraining the mass of the dark matter particle in this model. This is particularly true […]
