Primordial Magnetism in the CMB: Exact Treatment of Faraday Rotation and WMAP7 Bounds
Levon Pogosian, Amit P. S. Yadav, Yi-Fung Ng +1
Faraday rotation induced B-modes can provide a distinctive signature of primordial magnetic fields because of their characteristic frequency dependence and because they are only we…
It's Hard to Learn How Gravity and Electromagnetism Couple
Yi-Zen Chu, David M. Jacobs, Yifung Ng +1
We construct the most general effective Lagrangian coupling gravity and electromagnetism up to mass dimension 6 by enumerating all possible non-minimal coupling terms respecting bo…
Spectra of Magnetic Fields Injected during Baryogenesis
Yifung Ng, Tanmay Vachaspati
Helical magnetic fields are injected into the cosmic medium during cosmological baryogenesis and can potentially provide a useful probe of the early universe. We construct a model…
Formation of Non-Abelian Monopoles Connected by Strings
Yifung Ng, T. W. B. Kibble, Tanmay Vachaspati
We study the formation of monopoles and strings in a model where SU(3) is spontaneously broken to U(2)=[SU(2)\times U(1)]/\ZZ_2, and then to U(1). The first symmetry breaking gener…
