Three-dimensional rendering of the volume in the (μ, n, p) that can be reached by a stable, causal, and consistent EoS interpolating between known low- and high-density limits arising from chiral EFT and pQCD. The limits are depicted as the thick lines emerging from the lower-right and upper-left corners of the volume. (Left) Sample of fractal EoSs constructed using 10 iterations of the self-similar refinement process discussed in Section 2.2. The coloring of the EoSs is arbitrary and used solely to improve visual clarity. (Right) Sample of GP-bridge EoSs constructed from the self-similar EoSs by diffusive smoothing as described in Section 3.
