BMSFT纠缠熵的对数修正

Logarithmic Correction to BMSFT Entanglement Entropy

Reza Fareghbal, Pedram Karimi

摘要:

利用Rindler方法导出了二维BMS不变场论(BMSFT)的纠缠熵的对数修正。特别是,我们提出了一个通用的公式提取的对数修正的热熵和纠缠熵。我们还提出了一个与BTZ内视界熵的对数修正有关的CFT公式,在取适当的极限后得到了我们的公式。

英文摘要:

Using Rindler method we derive the logarithmic correction to the entanglement entropy of a two dimensional BMS-invariant field theory (BMSFT). In particular, we present a general formula for extraction of the logarithmic corrections to both the thermal and the entanglement entropies. We also present a CFT formula related to the logarithmic correction of the BTZ inner horizon entropy which results in our formula after taking appropriate limit.
