利用可积性研究AdS5/CFT4的Hagedorn温度

The Hagedorn temperature of AdS5/CFT4 via integrability

Troels Harmark, Matthias Wilhelm

摘要:

我们建立了一个框架,计算Hagedorn温度AdS 5/CFT 4通过可积性。具体地说,我们推导出了热力学Bethe方程,该方程在任意t Hooft耦合值下,给出了平面N=4超Yang-Mills理论的Hagedorn温度。我们通过相关的Y-系统在弱耦合下微扰求解这些方程,确认了树级和单圈阶的已知结果,并推导出先前未知的双环Hagedorn温度。最后,我们对有限耦合下方程的求解进行了评述。

英文摘要:

We establish a framework for calculating the Hagedorn temperature of AdS5/CFT4 via integrability. Concretely, we derive the thermodynamic Bethe ansatz equations that yield the Hagedorn temperature of planar N=4 super Yang-Mills theory at any value of the 't Hooft coupling. We solve these equations perturbatively at weak coupling via the associated Y-system, confirming the known results at tree-level and one-loop order as well as deriving the previously unknown two-loop Hagedorn temperature. Finally, we comment on solving the equations at finite coupling.
