Slow-roll analysis of double-field axion inflation
Slow-roll analysis of double-field axion inflation is a scholarly work, published in 2018 in ''Progress of Theoretical and Experimental Physics''. The main subjects of the publication include theoretical physics, field, axion, spectral line, Planck, mathematical physics, dark matter, quantum electrodynamics, physics, inflation, spectral index, spectral density, superstring theory, holographic principle, -, supergravity, and particle physics. The authors show that when the parameters are suitably chosen, there exist ranges of initial values of fields that can satisfy the constraints of Planck observations.
