[Lecture] "Tensionless String Spectra in AdS_3" by Prof. Rajesh Gopakumar
2018年6月30日 (土) 13:30 〜 14:30We examine the spectrum of superstrings on backgrounds of the form AdS_3\times S^3\times M at their minimal radius (or tensionless limit). We focus on a very natural subsector which consists of states at the bottom of the so-called spectrally flowed continuous representations. We find that this entire subsector matches precisely with that of a symmetric product CFT. This can be viewed as a signature of an unbroken Higher Spin Square (HSS) symmetry at this point. This HSS symmetry had previously appeared at a very different tensionless point in the parameter space of the string theory on AdS_3.
