Abstract: We estimate the free energy density of the thermal critical O(N) model for N = 1,2,3 in 3 ≤d≤4by solving the Kubo-Martin-Schwinger (KMS) condition numerically for the two-point functions offundamental scalars. We further compute thermal one-point functions of light operators and thethermal two-point function between fundamental scalars. We find agreement with known resultsfrom Monte Carlo simulations and previous results for the 3d Ising model, and we provide newpredictions for the critical O(2) and O(3) models.
