Non-minimal derivative coupling in Palatini cosmology: acceleration in chaotic inflation potential

Understand

NMDC-Palatini cosmology in slow-roll regime is of our interests.

• We present flat FLRW cosmological NMDC-Palatini field equations and acceleration condition.
• Late time trajectory is approximated.
• Chaotic inflation potential is considered here as it is viable in a range of positive coupling constant as constrained by CMB results.
