Hamilton-Jacobi analysis of noncanonical inflation in gravity: Constraints from Planck/ACT data, and theoretical bounds
Z. Ossoulian, T. Golanbari, Kh. Saaidi
The latest CMB data from ACT DR6, combined with Planck, DESI, and BICEP/Keck, indicate a slight upward shift in the scalar spectral index, placing several previously favored inflat…

Tsallis holographic inflation in gravity: CMB constraints, reheating, and swampland implications
S. Taghavi, T. Golanbari, Kh. Saaidi
Understanding how early-universe inflation may emerge from generalized holographic energy densities within modified gravity motivates the present analysis. We develop a self-consis…
