AI总结:

该研究以开实心环面为有限母体,重新探讨共形场论球区域的模流,得到简洁有限模生成元,将Rindler等构造恢复为奇异极限,还给出带电等标量示例并完善中心障碍。

摘要:

我们以开实心环面作为有限母体,重新研究共形场论中球区域的模流。其非奇异角演化给出形式极为简洁的有限模生成元,而到腔框架的精确共形映射可将Rindler、CHM及静止源球构造恢复为奇异极限。该有限母体还为复球流中的中心障碍提供正则完备化,并给出带电、狄拉克及非均匀标量的示例。

英文摘要:

Using the open solid torus as a finite parent, we revisit modular flow for spherical regions in conformal field theory. Its nonsingular angular evolution gives finite modular generators in a very simple form, while an exact conformal map to a cavity frame recovers the Rindler, CHM, and stationary-source ball constructions as singular limits. The same finite parent also provides a regular completion of the center obstruction in the complexified ball flow. Charged, Dirac, and inhomogeneous scalar examples are given.
