We propose a mechanism of symmetry breaking or restoration that can occur in the middle inflation due to coupling Gauss-Bonnet term charged scalar. The results an inflaton-dependent effective squared mass scalar, which change its sign (around symmetric point) during inflation. This lead spontaneous symmetry, restoration, if it is initially broken. show conditions under backreaction on inflationary background negligible, such predictions given model are unaffected by breaking/restoration process.

Particlelike solutions in SU(3) gauge Yang-Mills theory with color magnetic and electric fields sourced by a nonlinear spinor field are obtained. The asymptotic behavior of these is studied. It shown that the exhibits Coulomb behavior, one components behaves asymptotically as dipole. This allows to determine corresponding charge moment. profiles moment have global minima, which may be called gaps. relationship between total energy system physical reason for appearance mass, charge, gaps...

We further analyze phenomenological implications of double axion monodromy inflation proposed in Ref. Phys. Rev. D 104, L081302 (2021), gravitational wave physics. show that addition to chiral waves (GW) originating from gauge field instability, the model also predicts significant amount non-chiral, scalar-induced waves, both peaking at around same frequencies. find although GW density has much larger peak, non-chiral GWs can dominate away peak as they decay a slower rate. This provides an...
