A dilaton potential is adjusted to recently confirmed lattice QCD thermodynamics data in the temperature range where is the pseudo-critical temperature. The employed holographic model is based on a gravity–single-field dilaton dual. We discuss conditions for enforcing (for the pure gluon plasma) or avoiding (for the QCD quark–gluon plasma) a first-order phase transition, but still keeping a softest point (minimum of sound velocity).
