ACT-compatible Inflation in Scalar Field Coupled $f\left(Q,\tilde{R}\right)$ Gravity

Shin'ichi Nojiri, S. D. Odintsov, V. K. Oikonomou

In this work, we construct models compatible with ACT constraints on inflation in the framework of $f\left(Q,\tilde{R}\right)$ gravity, with $f(R)$ gravity coupled to a scalar fiel…
