Description:
Author(s): Stephon Alexander, Evan McDonough, and Robert Sims We study the production of primordial circular (“V-mode”) polarization in axion inflation coupled to fermions and gauge fields, with special attention paid to (p)reheating. We construct the power spectrum of V , and find a blue-tilted spectrum with index n V = 4 . This is independent of the dominant deca... [Phys. Rev. D 96, 063506] Published Tue Sep 12, 2017
