The inverse Borel transform is meromorphic except for a branch cut along the positive-real axis. The physical pressure is precisely nil at vanishing and acquires a small imaginary admixture at small temperature the latter indicating violations of thermal equilibrium (turbulences).12 pages, 4 figures, v2: slight modification of text, typo removed in Eq. 18, matches published versionHigh Energy Physics - Theorytext
