逆自举共形场论

Inverse Bootstrapping Conformal Field Theories

Wenliang Li

摘要:

本文提出了一种研究一般维数下共形场论的新方法。在共形bootstrap程序中,通常搜索满足交叉对称性的一致CFT数据。在新的方法中,我们扭转了逻辑和解释明显交叉对称的功能,共形数据的生成函数。通过扫描对称函数的空间可以获得物理CFTs。通过截断融合规则,我们能够集中在低位置的运营商,并推导出一些近似关系,他们的共形数据。结果表明,自由标量理论、二维极小模型连续函数、$ϕ^{4}$ Wilson-Fisher连续函数、Lee-Yang连续函数和Ising连续函数都与最小融合规则$ϕ_1\times ϕ_1=I+ϕ_2+T$(其中$ϕ_1,\,ϕ_2$是标量算子,$I$是恒等算子,$T$是应力张量)的普适关系相一致.

英文摘要:

We propose a novel approach to study conformal field theories (CFTs) in general dimensions. In the conformal bootstrap program, one usually searches for consistent CFT data that satisfy crossing symmetry. In the new approach, we reverse the logic and interpret manifestly crossing-symmetric functions as generating functions of conformal data. Physical CFTs can be obtained by scanning the space of symmetric functions. By truncating the fusion rules, we are able to concentrate on the low-lying operators and derive some approximate relations for their conformal data. It turns out that the free scalar theory, the 2d minimal model CFTs, the $ϕ^{4}$ Wilson-Fisher CFT, the Lee-Yang CFTs and the Ising CFTs are consistent with the universal relations from the minimal fusion rule $ϕ_1\times ϕ_1=I+ϕ_2+T$, where $ϕ_1,\,ϕ_2$ are scalar operators, $I$ is the identity operator and $T$ is the stress tensor.
