A step in flux to suppress axion isocurvature
The QCD axion in the pre-inflation scenario faces a stringent isocurvature constraint, which requires a relatively low Hubble scale during inflation. If the axion was heavier than the Hubble scale during inflation, its isocurvature is suppressed and the ...

Effects of the ekpyrotic mechanism on inflationary phase in loop quantum cosmologies
In bouncing cosmological models – whether classical or quantum – the big bang singularity is replaced by a regular bounce. A well-known challenge is controlling the growth of shear during the contracting phase, as the shear scales as $$a^{-6}$$ a - 6 ...

On inflation and torsion in cosmology
In a recent letter by H. Davoudiasl, R. Kitano, T. Li and H. Murayama ``The new Minimal Standard Model'' (NMSM) was constructed that incorporates new physics beyond the Minimal Standard Model (MSM) of particle physics. The authors follow the principle of minimal particle content and therefore adopt the viewpoint of particle physicists. It is shown that
