AdS4/CFT3中的扭转自由度

Torsional degrees of freedom in AdS4/CFT3

Anastasios C. Petkou

摘要:

我们讨论的扭转自由度的AdS 4/CFT 3的上下文中的全息含义,特别强调其作为载体的非平凡的引力磁场,即引力磁场的一部分,不确定的框架场的物理解释。作为一个具体的例子,我们提出了一个新的精确的四维挠率引力背景,并认为它对应于一个经历宇称对称破缺的三维系统的全息对偶。最后,我们比较了我们的新的引力背景与已知的虫洞解决方案-有和没有宇宙学常数-并认为,他们都可以统一在一个有趣的“卡尔布-雷蒙超导”框架。

英文摘要:

We discuss the holographic implications of torsional degrees of freedom in the context of AdS4/CFT3, emphasizing in particular their physical interpretation as carriers of the non-trivial gravitational magnetic field, i.e. the part of the gravitational magnetic field not determined by the frame field. As a concrete example we present a new exact 4d gravitational background with torsion and argue that it corresponds to the holographic dual of a 3d system undergoing parity symmetry breaking. Finally, we compare our new gravitational background with known wormhole solutions - with and without cosmological constant - and argue that they can all be unified under an intriguing "Kalb-Ramond superconductivity" framework.
