Constraints on Stable Scalar-Tensor Dark Energy from DESI Data and Solar System Tests
Husam Adam, Mark P. Hertzberg, Daniel Jiménez-Aguilar
We investigate the viability of scalar-tensor (quintessence) models of dark energy with a quartic polynomial nonminimal coupling to gravity and a linear scalar potential. The polyn…

Comparing Minimal and Non-Minimal Quintessence Models to 2025 DESI Data
Husam Adam, Mark P. Hertzberg, Daniel Jiménez-Aguilar +1
In this work we examine the 2025 DESI analysis of dark energy, which suggests that dark energy is evolving in time with an increasing equation of state . We explore a wide range…
