Filip Kos, David Poland, David Simmons-Duffin, Alessandro Vichi

摘要:

我们精确地确定了3d Ising,$O(2)$和$O(3)$模型的主标度维数和算子乘积展开(OPE)系数.我们改进了以前的研究,通过扫描可能的相对值的领先OPE系数,它结合了物理信息,只有一个单一的运营商在一个给定的缩放尺寸。尺度尺寸和OPE系数获得的三维伊辛模型,$(Δ_σ, Δ_ε,λ_{σσε}, λ_{εεε}) = (0.5181489(10), 1.412625(10), 1.0518537(41), 1.532435(19))$,给出最精确的测定这些数量的日期。

英文摘要:

We make precise determinations of the leading scaling dimensions and operator product expansion (OPE) coefficients in the 3d Ising, $O(2)$, and $O(3)$ models from the conformal bootstrap with mixed correlators. We improve on previous studies by scanning over possible relative values of the leading OPE coefficients, which incorporates the physical information that there is only a single operator at a given scaling dimension. The scaling dimensions and OPE coefficients obtained for the 3d Ising model, $(Δ_σ, Δ_ε,λ_{σσε}, λ_{εεε}) = (0.5181489(10), 1.412625(10), 1.0518537(41), 1.532435(19))$, give the most precise determinations of these quantities to date.
