Daimon v2.1: Scalar Field Viability and Phantom-Free Dynamics in an Informational Cosmological Model

We present DAIMON v2.1, an informationally modulated cosmological model refined to ensure physical viability through a phantom-free scalar field representation. While DAIMON v2 successfully reproduced the H(z) expansion history via a dynamic informational density Ω_info(z), its canonical scalar field reconstruction yielded intervals with w(z) < –1. In DAIMON v2.1, we adopt an energetic formulation of w(z) and refine key parameters to eliminate these phantom regimes. The resulting model exhibits monotonic scalar field evolution, a smooth potential V(ϕ), and stable dynamics across the cosmic timeline. Moreover, DAIMON v2.1 preserves good agreement with synthetic H(z) data while achieving consistency with canonical scalar-field theory. These results position DAIMON v2.1 as a theoretically robust alternative to ΛCDM, firmly grounded in an informational cosmological ontology.
