Effects of the inflaton mass on the pre-inflationary dynamics and primordial power spectra in loop quantum cosmology
Kui Xiao, Abolhassan Mohammadi, Hongwei Tan
Considering the mass parameters as free phenomenological parameters, we investigate inflation driven by a canonical scalar field with different potentials in LQC. We find that a sm…

A Starobinsky-like Potential in k-Essence Framework: Attractor Dynamics, Reheating, and Consistency with ACT DR6
Abolhassan Mohammadi, Yogesh, Hongwei Tan +1
The recent ACT DR6 has shifted the preferred value of the scalar spectral index upward so that many well-established inflationary models have been disfavoured, including the Starob…
