对数共形场论重力场新异常的捷径

Short-cut to new anomalies in gravity duals to logarithmic conformal field theories

Daniel Grumiller, Niklas Johansson, Thomas Zojer

摘要:

各种三维质量引力理论在理论上都是对数共形场论(LCFTs)的对偶。我们总结了这些设备的状态。LCFTs的特征在于中心荷值和所谓的“新异常”。我们采用一种捷径来计算这些新的异常在广义大质量引力和最近提出的高导数引力理论与全息c定理。这两种情况都允许LCFTs表现出有趣的特征,如秩三乔丹细胞或非零中心荷。最后,作为一个例子,我们详细讨论了部分无质量版本的新的大质量引力,一个理论与几个特殊的性质,我们称之为“部分无质量引力”。

英文摘要:

Various massive gravity theories in three dimensions are conjecturally dual to logarithmic conformal field theories (LCFTs). We summarise the status of these conjectures. LCFTs are characterised by the values of the central charges and the so-called "new anomalies". We employ a short-cut to calculate these new anomalies in generalised massive gravity and in the recently proposed higher-derivative gravity theories with holographic c-theorem. Both cases permit LCFTs exhibiting intriguing features, like rank three Jordan cells or non-zero central charges. Finally, as an example we discuss in some detail the partially massless version of new massive gravity, a theory with several special properties that we call "partially massless gravity".
