不可定向CFT中的宇宙动力学$_2$

Universal Dynamics in Non-Orientable CFT$_2$

Ioannis Tsiares

摘要:

定义在不可定向黎曼曲面上的二维共形场论(CFTs)服从与可定向情形类似的一致性Cardy条件。在实射影平面$\mathbb{RP}^2$上的原色的两点函数和克莱因瓶$\mathbb{K}^2$上的配分函数的背景下,我们重新审视了中心荷$c>1$的非理性理论的条件。使用Virasoro融合和模块化内核的非理性版本,我们推导出在大的共形维度的非定向CFT数据的通用表达式,假设标量原色的频谱中存在间隙。特别地,我们导出了OPE系数的平均轻-轻-重乘积$C_{LLH}\timesΓ_{H}$与$\mathbb{RP}^2$单点函数归一化的渐近公式,以及重标量原色的宇称加权密度(或等价于重$Γ_H^2$的密度)在有限中心荷下的渐近公式.我们讨论了结果的引力解释。

英文摘要:

Two-dimensional conformal field theories (CFTs) defined on non-orientable Riemann surfaces obey consistency Cardy conditions analogous to those in the orientable case. We revisit those conditions for irrational theories with central charge $c>1$ in the context of two-point functions of primaries on the Real Projective plane $\mathbb{RP}^2$ and the partition function on the Klein bottle $\mathbb{K}^2$. Using the irrational versions of the Virasoro fusion and modular kernels we derive universal expressions for the non-orientable CFT data at large conformal dimension, assuming a gap in the spectrum of scalar primaries. In particular, we derive asymptotic formulas at finite central charge for the averaged Light-Light-Heavy product $C_{LLH}\timesΓ_{H}$ of OPE coefficients with the $\mathbb{RP}^2$ one-point function normalizations, as well as for the parity-weighted density of heavy scalar primaries (or equivalently the density of heavy $Γ_H^2$). We discuss the gravitational interpretation of the results.
