The thermal bootstrap for the critical O(N) model
Published 1 Nov 2024 in hep-th | (2411.00978v3)
Abstract: We propose a numerical method to estimate one-point functions and the free-energy density of conformal field theories at finite temperature by solving the Kubo-Martin-Schwinger condition for the two-point functions of identical scalars. We apply the method for the critical O(N) model for N = 1,2,3 in 3 $\leq$ d $\leq$ 4. We find agreement with known results from Monte Carlo simulations and previous results for the 3d Ising model, and we provide new predictions for N = 2,3.

- Thermal OPE coefficients from Monte Carlo simulations require combining simulation results with the inversion formula, as done for the 3d3𝑑3d3 italic_d Ising model in Iliesiu et al. (2019).
- We exclude the case in which there are more operators of dimension Δ=dΔ𝑑\Delta=droman_Δ = italic_d. This is the case for the O(N)O𝑁\mathrm{O}(N)roman_O ( italic_N ) model that we are studying in this letter.
- We use conformal dimensions up to order O(ε3)𝑂superscript𝜀3O(\varepsilon^{3})italic_O ( italic_ε start_POSTSUPERSCRIPT 3 end_POSTSUPERSCRIPT ) and the CFT data needed to convert the stress-energy tensor coefficient to free energy up to order O(ε5)𝑂superscript𝜀5O(\varepsilon^{5})italic_O ( italic_ε start_POSTSUPERSCRIPT 5 end_POSTSUPERSCRIPT ).
