Abstract

In this study, we explore the reconstruction of a new agegraphic dark energy model in a flat Friedmann-Robertson-Walker spacetime by f(Q)f(Q) gravity framework, where QQ represents non-metricity. We assume that the scale factor follows a power-law and explore how this model aligns with the expanding universe. In this perspective, we develop a new agegraphic f(Q)f(Q) model and analyze the graphical behavior for cosmic evolution. We analyze physical characteristics of the model using the equation of state parameter, (ωDωD)(\omega_{D}-\omega^{\prime}_{D}) and the (rs)(r-s) planes. The equation of state parameter indicates a quintessence era characterized by accelerated expansion. The (ωDωD)(\omega_{D}-\omega^{\prime}_{D})-plane identifies the freezing region and the Chaplygin gas model is represented in the (rs)(r-s)-plane. Finally, we examine the stability of the non-interacting model by evaluating the squared speed of sound. Our findings show that the non-interacting new agegraphic dark energy model effectively resolves the cosmic coincidence problem.
