Stability and Thermodynamics of a Generalized Power-Law Dark Energy Model
A generalized power-law dark energy model, combining a linear pressure term with a power-law correction, admits a stable phantom-like accelerating attractor and satisfies the generalized second law precisely when the null energy condition holds.
