N=2极小模型全息的连续轨道

The Continuous Orbifold of N=2 Minimal Model Holography

Matthias R. Gaberdiel, Maximilian Kelm

摘要:

对于N=2的Kazama-Suzuki模型,在AdS_3上的高自旋对偶理论中,大能级极限可以用群U(N)解释为2N自由玻色子和费米子的连续轨道。特别是,我们表明,陪集表示的子集,对应于微扰的更高的自旋自由度,精确地描述了这个U(N)orbifold的无扭曲的部门。此外,我们确定扭曲的部门基态的orbifold与特定的陪集表示,并给出了各种证据,有利于这种识别。

英文摘要:

For the N=2 Kazama-Suzuki models that appear in the duality with a higher spin theory on AdS_3 it is shown that the large level limit can be interpreted as a continuous orbifold of 2N free bosons and fermions by the group U(N). In particular, we show that the subset of coset representations that correspond to the perturbative higher spin degrees of freedom are precisely described by the untwisted sector of this U(N) orbifold. We furthermore identify the twisted sector ground states of the orbifold with specific coset representations, and give various pieces of evidence in favour of this identification.
